Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM2BP4_StrongBS1_Supporting

The NM_001379110.1(SLC9A6):​c.1873A>G​(p.Ser625Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000331 in 1,209,642 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 1 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. S625S) has been classified as Likely benign.

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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.05008927).
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.0000179 (2/111780) while in subpopulation AMR AF = 0.00019 (2/10532). AF 95% confidence interval is 0.0000333. There are 0 homozygotes in GnomAd4. There are 0 alleles in the male GnomAd4 subpopulation. Median coverage is 22. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
