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]

This sequence change creates a premature translational stop signal (p.Gln501Lysfs*10) in the WDR35 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in WDR35 are known to be pathogenic (PMID: 22486404, 29068549). This variant is present in population databases (no rsID available, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with short rib polydactyly syndrome (PMID: 28400947). ClinVar contains an entry for this variant (Variation ID: 289210). For these reasons, this variant has been classified as Pathogenic. -
