Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_001013836.2(MAD1L1):​c.1998+17010G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.351 in 152,146 control chromosomes in the GnomAD database, including 10,350 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.35 (10350 hom., cov: 33)
• Consequence: MAD1L1 NM_001013836.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.41

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.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.04).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.457 is higher than 0.05.
