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 Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0017898381).
• BP6: Variant 15-73551046-G-A is Benign according to our data. Variant chr15-73551046-G-A is described in ClinVar as [Benign]. Clinvar id is 779894.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0998 is higher than 0.05.
