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 GeneticsMay 23, 2024The c.619T>C (p.S207P) alteration is located in exon 7 (coding exon 7) of the NKAIN2 gene. This alteration results from a T to C substitution at nucleotide position 619, causing the serine (S) at amino acid position 207 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
