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 Gene-Disease associations (from GenCC):

• male infertility with azoospermia or oligozoospermia due to single gene mutation

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• spermatogenic failure 25

  Inheritance: Unknown Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.00746 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• BS2: High AC in GnomAdExome4 at 44 Unknown,AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
