Coregulators involved in known and putative human genetic disease states
Coregulator | Human disease state | Relationship between coregulator and disease |
---|---|---|
SRC-26 | Von Gierke syndrome | Loss of SRC-2 results in reduced G6Pase in the liver*, phenocopying the glycogen storage disorder of this syndrome‡ |
SRC-310 | CACT deficiency | Loss of SRC-3* resembles CACT‡ deficiency with hypoketotic hypoglycaemia and muscle weakness |
PGC-1α13,14 | Genetic predisposition to obesity | Single nucleotide polymorphisms result in increased risk for diabetes mellitus and obesity‡ |
CBP and p30021,22 | Rubenstein–Taybi syndrome | Heterozygous disruption of CBP or p300 results in mental retardation and other defects due to reduced histone acetylation‡ |
MTA127 | Parkinson disease | MTA1 forms a complex with DJ1 and Pitx3 to control tyrosine hydroxylase expression§ |
TAZ28,29 | Thyroid gland dysgenesis | TAZ is required for maintenance of genes responsible for thyroid gland function‡§ |
Lipin-231,32 | Majeed syndrome | A missense mutation in lipin-2 is responsible for this syndrome and the mutation results in a loss of lipin-2 coactivator function‡ |
MRTF-A33,34 | Cardiac myocyte stress | MRTF-A coactivator function is required for sufficient SRF-mediated gene expression in response to cardiac myocyte mechanical stretching* |
N-CoR and SMRT39 | Resistance to thyroid hormone | Mutations in the thyroid hormone receptor can result in the retention of N-CoR and SMRT to the receptor when bound to agonist ligands‡ |
N-CoR and SMRT40 | Gene fusions in leukaemias | N-CoR–SMRT gene fusions result in inappropriate repression of genes required to maintain leukocytes in their differentiated state‡ |
HDAC444,45 | Brachydactyly mental retardation syndrome | Disruption of HDAC4 is responsible for bone defects observed in this syndrome‡ |
Multiple HDACs46,47 | Chronic obstructive pulmonary disease | Reduced expression of multiple HDACs results in reduced suppression of inflammation by glucocorticoids‡ |
