Genes affected

NCOA1 (HGNC:7668): (nuclear receptor coactivator 1) The protein encoded by this gene acts as a transcriptional coactivator for steroid and nuclear hormone receptors. It is a member of the p160/steroid receptor coactivator (SRC) family and like other family members has histone acetyltransferase activity and contains a nuclear localization signal, as well as bHLH and PAS domains. The product of this gene binds nuclear receptors directly and stimulates the transcriptional activities in a hormone-dependent fashion. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.2191A>G (p.I731V) alteration is located in exon 11 (coding exon 9) of the NCOA1 gene. This alteration results from a A to G substitution at nucleotide position 2191, causing the isoleucine (I) at amino acid position 731 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
