Abstract

BACKGROUND

Weill-Marchesani syndrome (WMS) belongs to the group of acromelic dysplasias, defined by short stature, brachydactyly and joint limitations. WMS is characterised by specific ophthalmological abnormalities, although cardiovascular defects have also been reported. Monoallelic variations in are associated with a dominant form of WMS, while biallelic variations in , and are responsible for a recessive form of WMS.

OBJECTIVE

Natural history description of WMS and genotype-phenotype correlation establishment.

MATERIALS AND METHODS

Retrospective multicentre study and literature review.

INCLUSION CRITERIA

clinical diagnosis of WMS with identified pathogenic variants.

RESULTS

61 patients were included: 18 individuals from our cohort and 43 patients from literature. 21 had variants in , 19 in , 19 in and 2 in . All individuals presented with eye anomalies, mainly spherophakia (42/61) and ectopia lentis (39/61). Short stature was present in 73% (from -2.2 to -5.5 SD), 10/61 individuals had valvulopathy. Regarding variants, patients with a variant located in transforming growth factor (TGF)-β-binding protein-like domain 5 (TB5) domain were significantly smaller than patients with variant outside TB5 domain (p=0.0040).

CONCLUSION

Apart from the ophthalmological findings, which are mandatory for the diagnosis, the phenotype of WMS seems to be more variable than initially described, partially explained by genotype-phenotype correlation.
