Genes affected

SLC9A9 (HGNC:20653): (solute carrier family 9 member A9) This gene encodes a sodium/proton exchanger that is a member of the solute carrier 9 protein family. The encoded protein localizes the to the late recycling endosomes and may play an important role in maintaining cation homeostasis. Mutations in this gene are associated with autism susceptibility 16 and attention-deficit/hyperactivity disorder. [provided by RefSeq, Mar 2012]

The c.1837C>T (p.P613S) alteration is located in exon 16 (coding exon 16) of the SLC9A9 gene. This alteration results from a C to T substitution at nucleotide position 1837, causing the proline (P) at amino acid position 613 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
