Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2024The c.1927G>A (p.V643M) alteration is located in exon 9 (coding exon 9) of the ADARB2 gene. This alteration results from a G to A substitution at nucleotide position 1927, causing the valine (V) at amino acid position 643 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
