Genes affected
MAD1L1 (HGNC:6762): (mitotic arrest deficient 1 like 1) MAD1L1 is a component of the mitotic spindle-assembly checkpoint that prevents the onset of anaphase until all chromosome are properly aligned at the metaphase plate. MAD1L1 functions as a homodimer and interacts with MAD2L1. MAD1L1 may play a role in cell cycle control and tumor suppression. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.2149G>A (p.V717M) alteration is located in exon 19 (coding exon 17) of the MAD1L1 gene. This alteration results from a G to A substitution at nucleotide position 2149, causing the valine (V) at amino acid position 717 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
