Genes affected

TRERF1 (HGNC:18273): (transcriptional regulating factor 1) This gene encodes a zinc-finger transcriptional regulating protein which interacts with CBP/p300 to regulate the human gene CYP11A1. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2014]

LOC105375061 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32887942).

The c.3560A>G (p.D1187G) alteration is located in exon 18 (coding exon 14) of the TRERF1 gene. This alteration results from a A to G substitution at nucleotide position 3560, causing the aspartic acid (D) at amino acid position 1187 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
