Genes affected

TEX9 (HGNC:29585): (testis expressed 9)

MNS1 (HGNC:29636): (meiosis specific nuclear structural 1) This gene encodes a protein highly similar to the mouse meiosis-specific nuclear structural 1 protein. The mouse protein was shown to be expressed at the pachytene stage during spermatogenesis and may function as a nuclear skeletal protein to regulate nuclear morphology during meiosis.

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.853

The c.1091G>C (p.R364T) alteration is located in exon 11 (coding exon 11) of the TEX9 gene. This alteration results from a G to C substitution at nucleotide position 1091, causing the arginine (R) at amino acid position 364 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
