Summary:
cDNA clones encoding the β-subunit of the pyruvate dehydrogenase (E1) component of the human pyruvate dehydrogenase complex were isolated from multiple sources and sequenced [Ho88, Koike88, Ho90, Chun90, Huh90].

The PDHB gene encoding the enzyme was localized on chromosome 3 [Chun90] and is composed of 10 exons and 9 introns [Koike90].

Mutations in the gene can cause pyruvate dehydrogenase deficiency [Brown04].
