Genes affected
ATP1B4 (HGNC:808): (ATPase Na+/K+ transporting family member beta 4) This gene has been found in all vertebrate genomes sequenced to date. However, this gene has undergone a change in function in placental mammals compared to other species. Specifically, in fish, avian, and amphibian species, this gene encodes plasma membrane-bound beta-subunits of Na,K-ATPase. In placental mammals, the encoded protein interacts with the nuclear transcriptional coregulator SKIP and may be involved in the regulation of TGF-beta signaling. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2023The c.133G>A (p.V45M) alteration is located in exon 2 (coding exon 2) of the ATP1B4 gene. This alteration results from a G to A substitution at nucleotide position 133, causing the valine (V) at amino acid position 45 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
