Genes affected

TEX15 (HGNC:11738): (testis expressed 15, meiosis and synapsis associated) This gene encodes a protein that is required for DNA double-strand break repair, chromosome synapsis, and meiotic recombination in spermatocytes. Male mice with a knockout of the orthologous gene are viable but sterile. Loss-of-function mutations in the orthologous mouse gene cause early meiotic arrest in spermatocytes, before the mid-pachytene stage. Naturally occurring mutations in this gene are associated with nonobstructive azoospermia. [provided by RefSeq, Apr 2017]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.06737393).

The c.8174G>T (p.G2725V) alteration is located in exon 3 (coding exon 3) of the TEX15 gene. This alteration results from a G to T substitution at nucleotide position 8174, causing the glycine (G) at amino acid position 2725 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
