Genes affected

REC114 (HGNC:25065): (REC114 meiotic recombination protein) The protein encoded by this gene is orthologous to the mouse meiotic recombination protein REC114, which is involved in DNA double-strand break formation during meiosis. The encoded protein is conserved in most eukaryotes and was first discovered and characterized in yeast. [provided by RefSeq, Feb 2017]

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=0.11306682).

The c.31C>G (p.L11V) alteration is located in exon 1 (coding exon 1) of the REC114 gene. This alteration results from a C to G substitution at nucleotide position 31, causing the leucine (L) at amino acid position 11 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
