Green List (high evidence)

Seven affected children from a consanguineous family homozygous for a missense variant. Affected children expressed a more severe phenotype than previously reported, including poor growth, developmental delay, brain dysmyelination, sensorineural hearing loss,nystagmus, progressive cholestatic liver disease, pancreatic insufficiency, hypoglycemia, anemia, intermittent proteinuria, recurrent bloodstream infections and chronic pulmonary disease. Carriers were asymptomatic (PMID: 30304524).

Homozygous missense variant in a patient with congenital nystagmus, profound congenital hearing impairment, primary amenorrhea, agenesis of the corpus callosum, and liver disease (PMID: 29232904)

Compound heterozygous variants identified in two siblings with failure to thrive (FTT), hypertriglyceridemia, developmental delay, liver dysfunction, lung cysts, and abnormal subcortical white matter (PMID: 27633801).

Note: loss of function is the mechanism of disease for the multisystem phenotypes mentioned in the above publications.

Dominant variants in YARS cause CMT in multiple patients. Functional studies performed in drosophila of 3 heterozygous missense variants recapitulate several features of human disease. Suspected gain of function disease mechanism (PMID: 19561293)
