Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2021The c.1327C>A (p.H443N) alteration is located in exon 5 (coding exon 5) of the ADARB2 gene. This alteration results from a C to A substitution at nucleotide position 1327, causing the histidine (H) at amino acid position 443 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
