Ivone Leong (Genomics England Curator)

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with an appropriate phenotype in OMIM but not in Gene2Phenotype. There is enough evidence for this gene to be Green. The gene has been given an Amber rating and will be promoted to Green at the next review.

Zornitza Stark (Australian Genomics)

Green List (high evidence)

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.
