Genes affected

NKAIN4 (HGNC:16191): (sodium/potassium transporting ATPase interacting 4) NKAIN4 is a member of a family of mammalian proteins (see NKAIN1; MIM 612871) with similarity to Drosophila Nkain and interacts with the beta subunit of Na,K-ATPase (ATP1B1; MIM 182330) (Gorokhova et al., 2007 [PubMed 17606467]).[supplied by OMIM, Jun 2009]

Ambry Genetics

Nov 24, 2024

The c.235A>G (p.I79V) alteration is located in exon 3 (coding exon 3) of the NKAIN4 gene. This alteration results from a A to G substitution at nucleotide position 235, causing the isoleucine (I) at amino acid position 79 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
