Genes affected

WDR36 (HGNC:30696): (WD repeat domain 36) 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. Mutations in this gene have been associated with adult-onset primary open-angle glaucoma (POAG). [provided by RefSeq, Jul 2008]

The missense variant p.N299S in WDR36 (NM_139281.3) has been previously reported in affected members of a family in heterozygous state with primary open angle galucoma (Monemi et al). It has been submitted to ClinVar as Pathogenic based on the same family. It is alternatively also called Asn355Ser. The p.N299S missense variant is predicted to be damaging by both SIFT and PolyPhen2. The asparagine residue at codon 299 of WDR36 is conserved in all mammalian species. The nucleotide c.896 in WDR36 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Likely Pathogenic. This variant was observed in heterozygous state in her unaffected father. -

Identified in an individual with primary open-angle glaucoma in published literature, but familial segregation data was not included (Monemi et al., 2005); Identified in a patient with congenital corneal opacity and scleralization of the peripheral cornea who also harbored a variant in the MYOC gene; each variant was inherited from a different unaffected parent (Patel et al., 2019); Published functional studies demonstrate that N355S was significantly more potent in promoting thromboxane A2 receptor-mediated G-alpha-q signalling than wild-type WDR36, however, the significance of this result is uncertain (Cartier et al., 2011); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; In-silico splice predictor analysis is inconclusive as to whether the variant alters gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown; This variant is associated with the following publications: (PMID: 19150991, 15677485, 21940795, 30653986) -
