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, 0.851

The c.1144T>A (p.F382I) alteration is located in exon 12 (coding exon 12) of the TEX9 gene. This alteration results from a T to A substitution at nucleotide position 1144, causing the phenylalanine (F) at amino acid position 382 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
