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]

Collection Method: clinical testing

The c.7906C>T (p.L2636F) alteration is located in exon 3 (coding exon 3) of the TEX15 gene. This alteration results from a C to T substitution at nucleotide position 7906, causing the leucine (L) at amino acid position 2636 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
