Typically present in young infants with abnormal liver function as FAH is mainly expressed in the liver.
Well established gene-disease association with multiple reported individuals having abnormal biochemical function of FAH.
LoF is the mechanism of disease. Gene Reviews reports many founder variants in different population.

Canavan disease is most prevalent in the AJ population however has been reported in other individuals as well. The most common variants in AJ population are p.Glu285Ala and p.Tyr231Ter (PMID:8252036). The most common variant reported in the non-Jewish population is p.Ala305Glu (PMID:20301412). All variants have been reported as pathogenic on ClinVar with at least 2/4 stars.

Variants have been reported in >10 individuals with elevated N-acetylaspartic acid (NAA) levels and LoF is the mechanism of disease.
