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]

TEX15 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.1062657E-6).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.757 is higher than 0.05.
