Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BP4

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.Ala9Ser variant in SLC9A6 is 0.307% 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). Computational analysis prediction tools suggest that the p.Ala9Ser variant does not have a deleterious impact; however this information does not predict clinical significance on its own (BP4). In summary, the p.Ala9Ser variant in SLC9A6 is classified as benign based on the ACMG/AMP criteria (BA1, BP4). LINK:https://erepo.genome.network/evrepo/ui/classification/CA295170/MONDO:0010278/016

Genes affected
SLC9A6 (HGNC:11079): (solute carrier family 9 member A6) This gene encodes a sodium-hydrogen exchanger that is amember of the solute carrier family 9. The encoded protein localizes to early and recycling endosomes and may be involved in regulating endosomal pH and volume. Defects in this gene are associated with X-linked syndromic cognitive disability, Christianson type. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Apr 2010]

Inborn genetic diseases Benign:1
Benign, criteria provided, single submitterclinical testingAmbry GeneticsJul 18, 2016This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
