Location of the NAA15 Mutations (image) Cold Spring Harbor Laboratory Share Print E-Mail Caption This is a schematic representation of the genomic structure of human NAA15, where solid blue rectangles indicate exons and the horizontal bars represent introns. Exons are the portion of the gene that contain instructions for making protein; introns are the intervening segments, which are ultimately edited out of the RNA that carries the gene's message to cellular protein factories. NAA15 variants with their relative positions in the gene are shown and the number of affected individuals with the specific variants are shown in parenthesis.
