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 GeneticsMay 31, 2023The c.542T>C (p.I181T) alteration is located in exon 6 (coding exon 6) of the NKAIN4 gene. This alteration results from a T to C substitution at nucleotide position 542, causing the isoleucine (I) at amino acid position 181 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
