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. [provided by RefSeq, Oct 2008]
TEX9 (HGNC:29585): (testis expressed 9)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.1344G>T (p.R448S) alteration is located in exon 9 (coding exon 9) of the MNS1 gene. This alteration results from a G to T substitution at nucleotide position 1344, causing the arginine (R) at amino acid position 448 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
