Position:

• chr7-135204389-G-T

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_014149.4(WDR91):​c.770C>A​(p.Pro257His) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P257L) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: WDR91 NM_014149.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 6.50

Genes affected

WDR91 (HGNC:24997): (WD repeat domain 91) Enables phosphatidylinositol 3-kinase regulator activity. Involved in early endosome to late endosome transport; regulation of cellular protein catabolic process; and regulation of phosphatidylinositol 3-kinase activity. Located in cytosol; early endosome membrane; and late endosome membrane. Is extrinsic component of endosome membrane. [provided by Alliance of Genome Resources, Apr 2022]
