Genes affected

NKAIN2 (HGNC:16443): (sodium/potassium transporting ATPase interacting 2) This gene encodes a transmembrane protein that interacts with the beta subunit of a sodium/potassium-transporting ATPase. A chromosomal translocation involving this gene is a cause of lymphoma. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2014]

The c.31A>G (p.I11V) alteration is located in exon 1 (coding exon 1) of the NKAIN2 gene. This alteration results from a A to G substitution at nucleotide position 31, causing the isoleucine (I) at amino acid position 11 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
