Genes affected

HIBCH (HGNC:4908): (3-hydroxyisobutyryl-CoA hydrolase) This gene encodes the enzyme responsible for hydrolysis of both HIBYL-CoA and beta-hydroxypropionyl-CoA. Mutations in this gene have been associated with 3-hyroxyisobutyryl-CoA hydrolase deficiency. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

HIBCH Gene-Disease associations (from GenCC):

• 3-hydroxyisobutyryl-CoA hydrolase deficiency

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Genomics England PanelApp, Orphanet, Ambry Genetics, Labcorp Genetics (formerly Invitae), G2P, ClinGen
