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.707C>G (p.P236R) alteration is located in exon 5 (coding exon 5) of the ATP1B4 gene. This alteration results from a C to G substitution at nucleotide position 707, causing the proline (P) at amino acid position 236 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
