Green List (high evidence)

Cholestasis has been reported in association with microvillus inclusion disease, but PMID: 28027573 and PMID: 27532546 also report cholestasis with normal or low γ‐glutamyltransferase activity, without diarrhoea, in a total of 13 unrelated individuals with biallelic variants in MYO5B. The youngest proband presented at 2 days of age, although in most cases the onset of symptoms was at more than one month of age.
Created: 14 Jan 2019, 8:45 a.m.

Mode of inheritance

Phenotypes
Cholestasis; Microvillus inclusion disease with cholestasis

Red List (low evidence)

Comment when marking as ready: Red on the basis of the phenotype and scope of the panel.

Comment on phenotypes: Microvillus inclusion disease 251850
Created: 27 Jul 2018, 10:31 a.m.
There is evidence of a gene:disease relationship, however I do not see that the phenotype of intractable diarrhoea is relevant to this panel. It is green on the GI epithelial barrier disorders panel which is more appropriate.
