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]

The c.3203A>G (p.Y1068C) alteration is located in coding exon 27 of the WDR35 gene. This alteration results from an A to G substitution at nucleotide position 3203, causing the tyrosine (Y) at amino acid position 1068 to be replaced by a cysteine (C). Based on data from gnomAD, the G allele has an overall frequency of 0.001% (2/251262) total alleles studied. The highest observed frequency was 0.012% (2/16148) of African alleles. This variant has been reported as a compound heterozygous finding in trans in a child diagnosed with cranioectodermal dysplasia/Sensenbrenner syndrome (Lin, 2013; Li, 2023). This has also been prenatally detected as a compound heterozygous finding in a male fetus with hydrops and polyhydramnios on ultrasound (Walczak-Sztulpa, 2020). This amino acid position is highly conserved in available vertebrate species. This alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as likely pathogenic.
