Variant 1-116124190-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_152367.3(MAB21L3):c.314G>A(p.Arg105Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000279 in 1,614,088 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/23 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. R105G) has been classified as Uncertain significance.

Ambry Genetics

Oct 26, 2022

The c.314G>A (p.R105Q) alteration is located in exon 4 (coding exon 3) of the MAB21L3 gene. This alteration results from a G to A substitution at nucleotide position 314, causing the arginine (R) at amino acid position 105 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
