Description

The allele frequency of the p.Arg51= variant in SLC9A6 is 0.058% in South Asian sub population in gnomAD, which is high enough to be classified as benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BA1). In summary, the p.Arg51= variant in SLC9A6 is classified as benign based on the ACMG/AMP criteria (BA1).
