The p.D1483A variant (also known as c.4448A>C), located in coding exon 22 of the ATP7A gene, results from an A to C substitution at nucleotide position 4448. The aspartic acid at codon 1483 is replaced by alanine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.
