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]
RNF217-AS1 (HGNC:50866): (RNF217 antisense RNA 1 (head to head))

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2022The c.472G>A (p.A158T) alteration is located in exon 4 (coding exon 4) of the NKAIN2 gene. This alteration results from a G to A substitution at nucleotide position 472, causing the alanine (A) at amino acid position 158 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
