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]

The c.979T>C (p.F327L) alteration is located in exon 8 (coding exon 7) of the SLC9B2 gene. This alteration results from a T to C substitution at nucleotide position 979, causing the phenylalanine (F) at amino acid position 327 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
