NCIt definition : Human HLCS wild-type allele is located in the vicinity of 21q22.13 and is approximately
242 kb in length. This allele, which encodes biotin-protein ligase protein, is involved
in the biotinylation of enzymes involved in gluconeogenesis, fatty acid synthesis
and branched chain amino acid catabolism. Loss of function mutations in the gene are
associated with holocarboxylase synthetase deficiency.;
