Gene Gene information from NCBI Gene database.
Entrez ID 3141
Gene name Holocarboxylase synthetase
Gene symbol HLCS
Synonyms (NCBI Gene)
HCS
Chromosome 21
Chromosome location 21q22.13
Summary This gene encodes an enzyme that catalyzes the binding of biotin to carboxylases and histones. The protein plays an important role in gluconeogenesis, fatty acid synthesis and branched chain amino acid catabolism. Defects in this gene are the cause of hol
