Abstract

Background: Schöpf-Schulz-Passarge syndrome (SSPS) is an autosomal recessive form of ectodermal dysplasia resulting from mutations in WNT10A.

Objectives: To document the spectrum of clinical features and search for pathogenic mutations in seven unrelated cases of SSPS.

Methods: Clinical examination of patients and Sanger sequencing of genomic DNA spanning the coding exons and flanking spice sites of WNT10A.

Results: Most subjects had bilateral eyelid cysts and some degree of palmoplantar keratoderma, although nail, hair, and teeth abnormalities were variably present. Bi-allelic pathogenic mutations in WNT10A were found in all seven subjects. New mutations comprised p.Glu390*, p.Ser270Arg, and p.Cys362Arg; the recurrent mutations were p.Cys107* and p.Ala131Thr.

Conclusions: This study reveals the range of ectodermal pathology in cases of SSPS that result from WNT10A mutations. Eyelid cysts provide a useful clinical clue to diagnosing SSPS which may be less rare than is currently appreciated.
