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]

Ambry Genetics

Aug 08, 2023

The c.1280T>C (p.I427T) alteration is located in exon 11 (coding exon 10) of the SLC9B2 gene. This alteration results from a T to C substitution at nucleotide position 1280, causing the isoleucine (I) at amino acid position 427 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
