Genes affected

WDR77 (HGNC:29652): (WD repeat domain 77) The protein encoded by this gene is an androgen receptor coactivator that forms a complex with protein arginine methyltransferase 5, which modifies specific arginines to dimethylarginines in several spliceosomal Sm proteins. The encoded protein may be involved in the early stages of prostate cancer, with most of the protein being nuclear-localized in benign cells but cytoplasmic in cancer cells. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]

The c.379A>G (p.I127V) alteration is located in exon 3 (coding exon 3) of the WDR77 gene. This alteration results from a A to G substitution at nucleotide position 379, causing the isoleucine (I) at amino acid position 127 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
