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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.11528534).

The c.3482T>A (p.I1161N) alteration is located in exon 18 (coding exon 14) of the TRERF1 gene. This alteration results from a T to A substitution at nucleotide position 3482, causing the isoleucine (I) at amino acid position 1161 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
