Variant 7-1898240-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_001013836.2(MAD1L1):c.1958C>G(p.Ser653Trp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000198 in 1,613,844 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. S653S) has been classified as Benign.

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.

The c.1958C>G (p.S653W) alteration is located in exon 18 (coding exon 16) of the MAD1L1 gene. This alteration results from a C to G substitution at nucleotide position 1958, causing the serine (S) at amino acid position 653 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
