Genes affected

EFCAB6 (HGNC:24204): (EF-hand calcium binding domain 6) This gene encodes a protein which directly binds the oncogene DJ-1 and androgen receptor to form a ternary complex in cells. This binding protein recruits histone-deacetylase complexes in order to repress transcription activity of androgen receptor. This protein may also play a role in spermatogenesis and fertilization. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

The c.4468A>G (p.I1490V) alteration is located in exon 32 (coding exon 30) of the EFCAB6 gene. This alteration results from a A to G substitution at nucleotide position 4468, causing the isoleucine (I) at amino acid position 1490 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
