Genes affected

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.

The c.1324G>C (p.A442P) alteration is located in exon 9 (coding exon 9) of the MNS1 gene. This alteration results from a G to C substitution at nucleotide position 1324, causing the alanine (A) at amino acid position 442 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
