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.

Ambry Genetics

Dec 13, 2023

The c.1475T>C (p.L492P) alteration is located in exon 15 (coding exon 13) of the MAD1L1 gene. This alteration results from a T to C substitution at nucleotide position 1475, causing the leucine (L) at amino acid position 492 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
