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 GeneticsNov 21, 2023The c.311G>A (p.R104H) alteration is located in exon 4 (coding exon 4) of the NKAIN4 gene. This alteration results from a G to A substitution at nucleotide position 311, causing the arginine (R) at amino acid position 104 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
