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

Jan 03, 2022

The c.233T>C (p.F78S) alteration is located in exon 3 (coding exon 3) of the NKAIN4 gene. This alteration results from a T to C substitution at nucleotide position 233, causing the phenylalanine (F) at amino acid position 78 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
