Genes affected

MAEL (HGNC:25929): (maelstrom spermatogenic transposon silencer) Predicted to enable sequence-specific DNA binding activity. Predicted to be involved in gamete generation; negative regulation of macromolecule metabolic process; and piRNA metabolic process. Predicted to act upstream of or within several processes, including homologous chromosome pairing at meiosis; intrinsic apoptotic signaling pathway in response to DNA damage; and negative regulation of macromolecule metabolic process. Predicted to be located in piP-body. Predicted to be active in P granule and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Apr 19, 2023

The c.146A>G (p.E49G) alteration is located in exon 2 (coding exon 2) of the MAEL gene. This alteration results from a A to G substitution at nucleotide position 146, causing the glutamic acid (E) at amino acid position 49 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
