NCIt definition : Human IARS1 wild-type allele is located in the vicinity of 9q22.31 and is approximately
84 kb in length. This allele, which encodes isoleucine-tRNA ligase, cytoplasmic protein,
plays a role in the synthesis of isoleucyl-tRNA. Mutations in the gene are associated
with growth retardation, impaired intellectual development, hypotonia, and hepatopathy
