Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_018365.4(MNS1):ā€‹c.1162C>Gā€‹(p.Arg388Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000235 in 1,613,660 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R388Q) has been classified as Uncertain significance.

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 GeneticsOct 14, 2023The c.1162C>G (p.R388G) alteration is located in exon 8 (coding exon 8) of the MNS1 gene. This alteration results from a C to G substitution at nucleotide position 1162, causing the arginine (R) at amino acid position 388 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
