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]

EFCAB6-AS1 (HGNC:39999): (EFCAB6 antisense RNA 1)

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.977

The c.4142A>G (p.Y1381C) alteration is located in exon 30 (coding exon 28) of the EFCAB6 gene. This alteration results from a A to G substitution at nucleotide position 4142, causing the tyrosine (Y) at amino acid position 1381 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
