Genetic Variant WDR83OS:p.Val91Leu (chr19-12668409-C-A) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

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

The NM_016145.4(WDR83OS):c.271G>T(p.Val91Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000186 in 1,613,496 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. V91M) has been classified as Uncertain significance.

Genes affected

WDR83OS (HGNC:30203): (WD repeat domain 83 opposite strand) Enables protein folding chaperone. Involved in protein insertion into ER membrane. Is integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

WDR83OS links:

WDR83 (HGNC:32672): (WD repeat domain 83) This gene encodes a member of the WD-40 protein family. The protein is proposed to function as a molecular scaffold for various multimeric protein complexes. The protein associates with several components of the extracellular signal-regulated kinase (ERK) pathway, and promotes ERK activity in response to serum or other signals. The protein also interacts with egl nine homolog 3 (EGLN3, also known as PHD3) and regulates expression of hypoxia-inducible factor 1, and has been purified as part of the spliceosome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]
