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

Jul 14, 2023

The c.1306G>C (p.E436Q) alteration is located in exon 9 (coding exon 8) of the M1AP gene. This alteration results from a G to C substitution at nucleotide position 1306, causing the glutamic acid (E) at amino acid position 436 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
