Genes affected
WDR35 (HGNC:29250): (WD repeat domain 35) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. Two patients with Sensenbrenner syndrome / cranioectodermal dysplasia (CED) were identified with mutations in this gene, consistent with a possible ciliary function.[provided by RefSeq, Sep 2010]

Cranioectodermal dysplasia 2;C3279792:Short-rib thoracic dysplasia 7 with or without polydactyly Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 06, 2017This sequence change creates a premature translational stop signal (p.Arg472*) in the WDR35 gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs767751856, ExAC 0.001%). This variant has not been reported in the literature in individuals with WDR35-related disease. Loss-of-function variants in WDR35 are known to be pathogenic (PMID: 21473986, 25908617). For these reasons, this variant has been classified as Pathogenic. -
