Neonatal cholestasisGene: GALM
This gene is associated with an appropriate phenotype in OMIM but not in Gene2Phenotype. There is enough evidence for this gene to be Green.
This gene was added to the Cholestasis panel by Zornitza Stark with the following review:
"Homozygous and compound heterozygous variants (missense, nonsense and frameshift) found in 8 Japanese patients from unrelated families with unexplained galactosaemia. (No variants in GALT, GALK1, and GALE). In vitro expression analysis and enzyme activity assay of the patients’ peripheral blood mononuclear cells showed total lack of or compromised expression of GALM protein. One homozygote for one of these variants p.(Gly142Arg) in gnomAD (African population). (Wada, Y. et al 2019; PMID: 30451973) Note only two individuals were reported as having transient cholestasis.
