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]

ENSG00000269590 (HGNC:):

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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0015950203).
• BP6: Variant 19-12669390-T-C is Benign according to our data. Variant chr19-12669390-T-C is described in ClinVar as [Benign]. Clinvar id is 2039517.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0164 (2500/152266) while in subpopulation NFE AF= 0.0243 (1656/68022). AF 95% confidence interval is 0.0234. There are 21 homozygotes in gnomad4. There are 1213 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 21 AR gene
