Zori–Stalker–Williams syndrome
Zori–Stalker–Williams syndrome is an ultra-rare multiple congenital anomalies syndrome defined by relative macrocephaly, pectus excavatum, short stature, dysplastic nails and a motor developmental delay that usually resolves during childhood.Zori–Stalker–Williams 综合征是一种极罕见的多发先天畸形综合征,以相对大头畸形、漏斗胸、身材矮小、指甲发育不良及通常在儿童期缓解的运动发育迟缓为特征。
The syndrome was described once in 1992 and has not been further characterised in the literature since then, so its cause, inheritance and natural history remain incompletely established.该综合征仅在 1992 年被描述过一次,此后文献未见进一步研究,因此其病因、遗传方式与自然史仍未完全确立。
Terminology and classification
- The descriptive name pectus excavatum-macrocephaly-dysplastic nails syndrome is used by Orphanet, MONDO and MedGen, while Zori–Stalker–Williams syndrome remains the common eponym.Orphanet、MONDO 与 MedGen 使用描述性名称「漏斗胸-大头畸形-指甲发育不良综合征」,而 Zori–Stalker–Williams 综合征仍是常用人名名称。
- The eponym honours the three researchers, Zori, Stalker and Williams, who first recognised and reported the combination of features in 1992.该人名名称纪念最早于 1992 年识别并报告这一组特征的 Zori、Stalker 与 Williams 三位研究者。
- OMIM lists the phenotype as 600399, MONDO assigns MONDO:0010883 and Orphanet uses ORPHA:2835, and these three identifiers refer to the same clinical entity.OMIM 将该表型编为 600399,MONDO 编为 MONDO:0010883,Orphanet 编为 ORPHA:2835,三套标识指向同一临床实体。
- MeSH catalogues the condition as C536728, UMLS as C2931302, GARD as 374 and SNOMED CT as 763863002, which allows the syndrome to be retrieved across clinical terminology systems.MeSH 编为 C536728,UMLS 编为 C2931302,GARD 编为 374,SNOMED CT 编为 763863002,便于在各类临床术语系统中检索该综合征。
- ICD-10 does not have a specific code and Orphanet attributes the broader code Q87.5, while ICD-11 has no dedicated code for the syndrome at all.ICD-10 无专属编码,Orphanet 将其归入较宽泛的 Q87.5,而 ICD-11 完全没有为该综合征单列编码。
- Orphanet classifies ORPHA:2835 as a historical entity, a status reserved for disorders that are no longer actively annotated because the literature has not expanded.Orphanet 将 ORPHA:2835 标记为「历史实体」,该状态用于因文献长期未扩展而不再积极注释的病种。
- MedGen places the condition within the hierarchy of genetic multiple congenital anomalies and dysmorphic syndromes without intellectual disability, which distinguishes it from metabolic and neurodegenerative disorders.MedGen 将该病归入「不伴智力障碍的遗传性多发先天畸形与面容异常综合征」层级,从而与代谢病及神经变性疾病区分。
- Because the original report described a familial short stature syndrome with pectus abnormalities, the term familial short stature, developmental delay, pectus abnormalities, distinctive facies and dysplastic nails is also used as a synonym.由于原始报告描述的是伴漏斗胸异常的家族性身材矮小综合征,「家族性身材矮小、发育迟缓、漏斗胸异常、特殊面容与指甲发育不良」也被用作同义词。
History
- Zori, Stalker and Williams reported the syndrome in 1992 as a previously unrecognised familial pattern of pectus excavatum, macrocephaly, short stature and dysplastic nails.Zori、Stalker 与 Williams 于 1992 年报告该综合征,将其描述为此前未被认识的漏斗胸、大头畸形、身材矮小与指甲发育不良的家族性组合。
- The eponym Zori–Stalker–Williams syndrome entered the literature through that report, and it is still the name used in most databases and reviews.Zori–Stalker–Williams 综合征这一人名名称因该报告进入文献,至今仍是多数数据库与综述采用的名称。
- Later nosology replaced the eponym with the descriptive label pectus excavatum-macrocephaly-dysplastic nails syndrome, following the trend to name rare syndromes by their cardinal features.后来的疾病命名学以描述性名称「漏斗胸-大头畸形-指甲发育不良综合征」取代人名名称,符合按核心特征命名罕见综合征的趋势。
- No second family or case series was published after the original description, and MONDO and Orphanet both state that there have been no further descriptions in the literature since 1992.原始描述之后未见第二个家系或病例系列发表,MONDO 与 Orphanet 均指出自 1992 年以来文献中没有进一步描述。
- The absence of follow-up literature means that the original phenotype has never been re-examined with modern imaging, exome sequencing or standardised developmental assessment.缺乏后续文献意味着原始表型从未用现代影像学、外显子组测序或标准化发育评估重新检视。
- OMIM has retained 600399 as a phenotype entry without a known molecular basis, and Orphanet's historical flag reflects the same stagnation rather than a judgment that the entity does not exist.OMIM 保留 600399 作为尚无分子基础的表型条目,Orphanet 的历史标记反映的是同样的研究停滞,而非判定该实体不存在。
Epidemiology
- No population-based study has measured the birth prevalence of Zori–Stalker–Williams syndrome, and the figure of about one per million that appears in Wikidata is a database estimate rather than a measured rate.尚无基于人群的研究测定 Zori–Stalker–Williams 综合征的出生患病率,Wikidata 中约百万分之一的数字属于数据库估计而非实测率。
- The published literature contains only the 1992 index description, so the total number of affected individuals worldwide is unknown and almost certainly under-ascertained.已发表文献仅有 1992 年的首例描述,全球受累人数未知,且几乎可以肯定被低估。
- There is no evidence of a geographic cluster, ethnic predilection or sex bias, and reported cases are too few to estimate any of these distributions.目前没有地理聚集、种族易感或性别偏倚的证据,报告病例过少也无法估计这些分布。
- Mild expression, with short stature and nail changes but only transient motor delay, may explain why affected adults are never referred to genetics clinics.轻症表现——身材矮小与指甲改变但仅有短暂运动迟缓——可能解释了为何受累成人从未被转诊至遗传门诊。
- No mortality, morbidity or life-expectancy data exist, and the oldest reported individuals are not documented beyond the original family.没有死亡率、发病率或预期寿命数据,原始家系之外的老年受累者也未见记录。
- Because motor delay resolves during childhood according to the original description, the condition is not classified as a progressive neurodevelopmental disorder.根据原始描述,运动迟缓在儿童期缓解,因此该病未被归类为进展性神经发育障碍。
Pathophysiology
- The cause is unknown, and no pathogenic variant, candidate gene, chromosomal locus or environmental exposure has been established.病因未知,尚未确定致病性变异、候选基因、染色体位点或环境暴露。
- Wikipedia states that the syndrome is believed to be inherited in an autosomal dominant pattern, but Orphanet and MedGen record the mode of inheritance as unknown.维基百科称该综合征被认为呈常染色体显性遗传,但 Orphanet 与 MedGen 将其遗传方式记录为未知。
- Autosomal dominant inheritance would imply a 50% recurrence risk for the offspring of an affected person, whereas an unknown mode leaves genetic counselling probabilistic rather than deterministic.若为常染色体显性遗传,患者子代的复发风险为 50%,而遗传方式未知时,遗传咨询只能给出概率性而非确定性结论。
- The combination of macrocephaly, pectus excavatum, short stature and nail dysplasia suggests a disturbance of a shared developmental field, but no tissue, biochemical or molecular study has tested this hypothesis.大头畸形、漏斗胸、身材矮小与指甲发育不良的组合提示共同发育场受到干扰,但尚无组织学、生化或分子研究检验这一假说。
- Macrocephaly is described as relative rather than progressive, and the original report did not document hydrocephalus, brain malformation or raised intracranial pressure.大头畸形被描述为相对性而非进行性,原始报告也未记录脑积水、脑畸形或颅内压升高。
- There is no known association with cardiac, renal, hepatic, immune or haematological disease, which argues against a broad peroxisomal or metabolic defect.目前没有与心脏、肾脏、肝脏、免疫或血液疾病相关的已知联系,这不支持广泛的过氧化物酶体或代谢缺陷。
Clinical features
- Relative macrocephaly is the most consistent cranial feature, and the head appears large in proportion to a short-statured body rather than showing absolute megalencephaly.相对大头畸形是最一致的颅部特征,头部相对于矮小的身材显得较大,而非绝对性巨脑。
- Craniofacial findings include a broad or prominent forehead, prominent supraorbital ridges, a depressed nasal bridge, a short nose, malar flattening and hypoplasia of the zygomatic bone.颅面表现包括宽大或突出的前额、突出的眶上嵴、鼻梁凹陷、短鼻、面颊变平以及颧骨发育不良。
- Pectus excavatum is a cardinal feature and may be isolated or part of a more generalised chest wall abnormality, and its severity varies between affected relatives.漏斗胸是核心特征,可为孤立表现或更广泛胸壁异常的一部分,其严重程度在受累亲属之间有所不同。
- Short stature is described as familial, suggesting that the height deficit tracks within families rather than following a single uniform growth pattern.身材矮小被描述为家族性,提示身高缺陷在家族内聚集,而非遵循单一均一的生长模式。
- Nail dysplasia mainly affects the toenails, with hypoplastic nails reported alongside broader nail dysplasia, and the change is developmental rather than inflammatory.指甲发育不良主要累及趾甲,除指甲发育不良外还可见趾甲发育不全,属发育性而非炎症性改变。
- Global developmental delay and hypotonia were part of the original phenotype, and the motor delay is reported to resolve during childhood while cognitive outcome is not well documented.全面发育迟缓与肌张力低下属于原始表型,运动迟缓据报在儿童期缓解,而认知结局缺乏充分记录。
- Distinctive facies, short stature and dysplastic nails together form the recognisable gestalt, but none of these features is specific enough to diagnose the syndrome in isolation.特殊面容、身材矮小与指甲发育不良共同构成可识别的整体印象,但单凭其中任何一项都不足以诊断该综合征。
- Named complications are primarily cosmetic and orthopaedic, including chest wall deformity, short stature and nail changes, and there is no documented predisposition to infection, malignancy or organ failure.具名并发症主要是外观与骨科问题,包括胸壁畸形、身材矮小与指甲改变,未记录对感染、恶性肿瘤或器官衰竭的易感倾向。
Diagnosis
- There are no published diagnostic criteria, biomarkers or imaging hallmarks, so diagnosis rests on recognising the characteristic combination and excluding phenocopies.尚无发表的诊断标准、生物标志物或影像学标志,诊断依赖于识别特征性组合并排除表型模仿病。
- Standardised Human Phenotype Ontology terms can document the phenotype, including HP:0000256 for macrocephaly, HP:0000767 for pectus excavatum, HP:0004322 for short stature and HP:0002164 for nail dysplasia.可用标准化的人类表型本体术语记录表型,包括大头畸形 HP:0000256、漏斗胸 HP:0000767、身材矮小 HP:0004322 与指甲发育不良 HP:0002164。
- Chromosomal microarray or karyotype should be performed to exclude a contiguous gene deletion or duplication that can mimic the combination of macrocephaly, short stature and nail changes.应行染色体微阵列或核型分析,以排除可模仿大头畸形、身材矮小与指甲改变组合的相邻基因缺失或重复。
- Exome or genome sequencing may be offered, but a negative result does not exclude the syndrome because no causal gene has been identified.可提供外显子组或基因组测序,但阴性结果不能排除该综合征,因为尚未发现致病基因。
- Noonan syndrome is the closest differential and is distinguished by PTPN11 or related RASopathy variants, pulmonary valve stenosis, hypertrophic cardiomyopathy and lymphatic dysplasia rather than isolated nail dysplasia.Noonan 综合征是最接近的鉴别诊断,其区别在于 PTPN11 或相关 RASopathy 变异、肺动脉瓣狭窄、肥厚型心肌病与淋巴发育异常,而非孤立性指甲发育不良。
- Costello syndrome and cardiofaciocutaneous syndrome also cause short stature, pectus deformity and distinctive facies, but they show loose skin, papillomata or keratosis pilaris and a high rate of cardiac hypertrophy.Costello 综合征与心面皮肤综合征同样造成身材矮小、漏斗胸畸形与特殊面容,但前者有皮肤松弛与乳头状瘤,后者有毛周角化,且两者心脏肥厚发生率较高。
- Coffin–Siris syndrome overlaps through fifth-digit nail hypoplasia and developmental delay, but it usually includes coarse facies, sparse hair and intellectual disability and is associated with ARID1B or other SWI/SNF genes.Coffin–Siris 综合征因第五指指甲发育不全与发育迟缓而重叠,但通常伴粗陋面容、毛发稀疏与智力障碍,并与 ARID1B 等 SWI/SNF 基因相关。
- Rubinstein–Taybi syndrome is distinguished by broad thumbs and halluces, a beaked nose and CREBBP or EP300 variants, none of which has been described in Zori–Stalker–Williams syndrome.Rubinstein–Taybi 综合征以宽拇指与宽拇趾、鹰钩鼻及 CREBBP 或 EP300 变异相区分,这些特征均未在 Zori–Stalker–Williams 综合征中描述。
- Because the phenotype is mild and the literature sparse, many affected people are probably labelled as familial short stature or isolated pectus excavatum and never receive a syndromic diagnosis.由于表型轻微且文献稀少,许多受累者可能被标记为家族性身材矮小或孤立性漏斗胸,从未获得综合征诊断。
Management
- There is no disease-specific therapy, and management is multidisciplinary, involving clinical genetics, paediatrics, orthopaedics, plastic surgery and developmental services as needed.目前没有疾病特异性治疗,处理为多学科协作,按需涉及临床遗传、儿科、骨科、整形外科与发育服务。
- Pectus excavatum should be assessed for cardiopulmonary compression and cosmetic impact, with CT-derived Haller index and cardiopulmonary testing used when symptoms or severe deformity are present.漏斗胸应评估心肺压迫与外观影响,有症状或严重畸形时使用 CT 计算的 Haller 指数与心肺功能检查。
- Symptomatic or severe pectus excavatum can be repaired by the Nuss procedure, introduced in 1998, or by the older Ravitch operation, and repair is offered on functional or aesthetic grounds rather than as disease-specific treatment.有症状或严重的漏斗胸可行 1998 年问世的 Nuss 手术或较早的 Ravitch 手术,修复依据为功能或外观需要,而非疾病特异性治疗。
- Hypotonia and motor delay warrant physiotherapy and occupational therapy, with early developmental intervention aimed at gross motor skills, balance and school participation.肌张力低下与运动迟缓需物理治疗与作业治疗,早期发育干预应针对粗大运动、平衡与入学参与。
- Growth should be plotted on standard charts, and endocrine assessment is reserved for children with severe or progressive short stature rather than offered routinely.应按标准生长曲线监测身高,内分泌评估仅用于严重或进展性身材矮小儿童,不作常规推荐。
- Dysplastic nails are managed conservatively with podiatric care, and surgery is rarely indicated unless nails cause pain, recurrent infection or functional limitation.发育不良的指甲以足病护理保守处理,除非引起疼痛、反复感染或功能受限,否则很少需要手术。
- Genetic counselling should explain that autosomal dominant inheritance has been proposed but not proven, so recurrence risk cannot be stated with certainty.遗传咨询应说明常染色体显性遗传仅为推测而未被证实,因此无法确定复发风险。
- The prognosis for motor development appears favourable because the delay resolves in childhood, but adult height, chest symptoms and long-term health have not been studied.运动发育预后看来良好,因为迟缓在儿童期缓解,但成年身高、胸部症状与长期健康尚未被研究。
Research and controversies
- The central unresolved question is the molecular basis, and no gene has been implicated despite the syndrome being listed in OMIM for decades.核心未决问题是分子基础,尽管该综合征列入 OMIM 已数十年,仍无任何基因被确认。
- Exome or genome sequencing of the original family, if samples are still available, would be the most direct way to identify a candidate variant or to test for a microdeletion.若原始家系样本仍可获取,对其行外显子组或基因组测序将是寻找候选变异或检验微缺失的最直接方法。
- Reanalysis through Matchmaker Exchange or an undiagnosed diseases programme could connect isolated contemporary cases that never entered the literature.通过 Matchmaker Exchange 或未诊断疾病项目重新分析,可把从未进入文献的现代孤立病例联系起来。
- ClinicalTrials.gov contains no interventional study for Zori–Stalker–Williams syndrome as of October 2026, which reflects both rarity and the absence of a validated target.截至 2026 年 10 月,ClinicalTrials.gov 没有针对 Zori–Stalker–Williams 综合征的干预性研究,这既反映其罕见性,也反映缺乏经验证的靶点。
- One hypothesis is that the condition belongs to the RASopathy spectrum, but this is speculative because no PTPN11, SOS1, RAF1, HRAS or related variant has been reported.一种假说认为该病属于 RASopathy 谱系,但这只是推测,因为尚未报告 PTPN11、SOS1、RAF1、HRAS 或相关变异。
- The 1992 report has never been replicated, and modern deep phenotyping is needed to determine whether the eponym describes one disorder or a heterogeneous group of short stature syndromes.1992 年的报告从未被重复,需要现代深度表型分析来判断该人名名称描述的是一种疾病还是一组异质性身材矮小综合征。
- Orphanet's historical status is a call for re-annotation rather than evidence of extinction, and new case reports with photographs, growth data and genetic testing would be sufficient to reopen the entry.Orphanet 的历史状态是重新注释的呼吁,而非疾病消失的证据,新的病例报告若含照片、生长数据与基因检测,足以重启该条目。
