Variant 8-37830832-T-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_032777.10(ADGRA2):c.841T>C(p.Trp281Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic 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. W281C) has been classified as Uncertain significance.

The c.841T>C (p.W281R) alteration is located in exon 7 (coding exon 7) of the ADGRA2 gene. This alteration results from a T to C substitution at nucleotide position 841, causing the tryptophan (W) at amino acid position 281 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
