Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_002358.4(MAD2L1):c.376G>T(p.Asp126Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.00000658 in 152,076 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D126N) has been classified as Uncertain significance.

Genes affected

MAD2L1 (HGNC:6763): (mitotic arrest deficient 2 like 1) MAD2L1 is a component of the mitotic spindle assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. MAD2L1 is related to the MAD2L2 gene located on chromosome 1. A MAD2 pseudogene has been mapped to chromosome 14. [provided by RefSeq, Jul 2008]
