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 Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.077231675).

The c.3746C>G (p.S1249C) alteration is located in exon 25 (coding exon 24) of the TEX14 gene. This alteration results from a C to G substitution at nucleotide position 3746, causing the serine (S) at amino acid position 1249 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
