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 Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.006213367).
• BP6: Variant 17-58561539-G-A is Benign according to our data. Variant chr17-58561539-G-A is described in ClinVar as [Benign]. Clinvar id is 779460.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00574 (874/152322) while in subpopulation AFR AF= 0.00924 (384/41578). AF 95% confidence interval is 0.00847. There are 5 homozygotes in gnomad4. There are 438 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 5 AR gene
