Genes affected

M1AP (HGNC:25183): (meiosis 1 associated protein) This gene encodes a protein that is likely to function in progression of meiosis. A similar protein in mouse plays a role in gametogenesis in both sexes. Alternate splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2013]

Ambry Genetics

Oct 12, 2022

The c.1205C>T (p.T402M) alteration is located in exon 8 (coding exon 7) of the M1AP gene. This alteration results from a C to T substitution at nucleotide position 1205, causing the threonine (T) at amino acid position 402 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
