Overview on human disorders in relation to choline metabolism

	gene (mode of inheritance)	protein	main clinical findings
neurotransmitter biosynthesis	SLC5A7 (ar, ad)	CHT1 = high affinity choline transporter	congenital myasthenic syndrome (muscular hypotonia and weakness, apnoea, ptosis, poor sucking and swallowing; ar), hereditary motor neuronopathy (ad)
	CHAT (ar)	CHAT = choline acetyltransferase	congenital myasthenic syndrome (see above)
phospholipid biosynthesis	SLC44A1 (ar)	CTL1 = choline transporter like protein 1	postural orthostatic tachycardia syndrome
	CHKB (ar, SNPs)	CHKB = Choline kinase beta	muscular dystrophy, susceptibility to narcolepsy (SNPs)
	PCYT1A (ar)	PCYT1A = choline‐phosphate cytidyltransferase A	cone‐rod dystrophy, either isolated or in combination with spondylometaphyseal dysplasia, congenital lipodystrophy, fatty liver, severe insulin resistance, and diabetes
	CEPT1 (ar)	C/EPT1 = choline/ethanolamine phosphotransferase 1	hereditary spastic paraparesis, developmental delay, intellectual disability, dysarthria, retinal pigmentary abnormalities and cone rod dystrophy
pyrimidine metabolism	CAD (ar)	CAD = carbamoyl phosphate synthetase/ aspartate transcarbamoylase/ dihydroorotase	epileptic encephalopathy, anaemia, intellectual disability, loss of skills
	DHODH (ar)	DHODH = dihydroorotate dehydrogenase	postaxial acrofacial dysostosis (Miller syndrome)
	UMPS (ar)	UMPS = uridine monophosphate synthase	anaemia
methylation	ALDH7A1 (ar)	ALDH7A1 = aldehyde dehydrogenase	pyridoxine dependant epilepsy, intellectual disability
	DMGDH (ar)	DMGDH = Dimethylglycine dehydrogenase	malodour
	GNMT	Glycine N‐methyltransferase deficiency	mild hepatomegaly and chronic elevation of serum transaminases
fish odour disease	FMO3 (ar)	FMO3 = flavin‐containing monooxygenase	malodour
