Genetic Variant TEX15:p.Gly3086Ser (chr8-30837028-C-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001350162.2(TEX15):c.9256G>A(p.Gly3086Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G3086R) has been classified as Uncertain significance.

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]
