Genes affected
SLC9B2 (HGNC:25143): (solute carrier family 9 member B2) Sodium hydrogen antiporters, such as NHEDC2, convert the proton motive force established by the respiratory chain or the F1F0 mitochondrial ATPase into sodium gradients that drive other energy-requiring processes, transduce environmental signals into cell responses, or function in drug efflux (Xiang et al., 2007 [PubMed 18000046]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.1350G>T (p.K450N) alteration is located in exon 11 (coding exon 10) of the SLC9B2 gene. This alteration results from a G to T substitution at nucleotide position 1350, causing the lysine (K) at amino acid position 450 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
