Genes affected

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]

Ambry Genetics

Oct 06, 2022

The c.121C>G (p.L41V) alteration is located in exon 4 (coding exon 2) of the WDR83 gene. This alteration results from a C to G substitution at nucleotide position 121, causing the leucine (L) at amino acid position 41 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
