Genes affected

TEX14 (HGNC:11737): (testis expressed 14, intercellular bridge forming factor) The protein encoded by this gene is necessary for intercellular bridges in germ cells, which are required for spermatogenesis. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2011]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-58587937-CTGCCGGTGGCT-C is Pathogenic according to our data. Variant chr17-58587937-CTGCCGGTGGCT-C is described in ClinVar as [Pathogenic]. Clinvar id is 440758.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr17-58587937-CTGCCGGTGGCT-C is described in Lovd as [Likely_pathogenic].
