Variant 7-23300868-A-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_138446.2(MALSU1):c.286A>T(p.Met96Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000186 in 1,613,902 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M96V) has been classified as Uncertain significance.

Dec 21, 2023

The c.286A>T (p.M96L) alteration is located in exon 2 (coding exon 2) of the MALSU1 gene. This alteration results from a A to T substitution at nucleotide position 286, causing the methionine (M) at amino acid position 96 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
