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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.507C>A (p.S169R) alteration is located in exon 5 (coding exon 5) of the NKAIN4 gene. This alteration results from a C to A substitution at nucleotide position 507, causing the serine (S) at amino acid position 169 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
