Variant 10-1199999-C-G 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_018702.4(ADARB2):c.1831G>C(p.Ala611Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000635 in 1,573,770 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. A611V) has been classified as Uncertain significance.

Ambry Genetics

Jul 19, 2023

The c.1831G>C (p.A611P) alteration is located in exon 8 (coding exon 8) of the ADARB2 gene. This alteration results from a G to C substitution at nucleotide position 1831, causing the alanine (A) at amino acid position 611 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
