Green List (high evidence)

Classified Definitive by ClinGen Aminoacidopathy GCEP on 25/01/2019 - https://search.clinicalgenome.org/CCID:004917

Well established gene-disease association.
Reported as an inborn error of creatine metabolism.
The two most commonly reported variants are p.Trp20Ser (c.59G>C) and c.327G>A (p.Lys109=). Both variants are pathogenic on ClinVar (>2 stars) and is classified pathogenic by the ClinGen Cerebral Creatine Deficiency Syndromes Variant Curation Expert Panel (FDA recognised database).
