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]

The c.373G>C (p.A125P) alteration is located in exon 3 (coding exon 3) of the ATP1B4 gene. This alteration results from a G to C substitution at nucleotide position 373, causing the alanine (A) at amino acid position 125 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
