Invitae RCV000672049 SCV001225560 pathogenic Metachromatic leukodystrophy 2019-10-17 criteria provided, single submitter clinical testing This sequence change replaces histidine with tyrosine at codon 399 of the ARSA protein (p.His399Tyr). The histidine residue is highly conserved and there is a moderate physicochemical difference between histidine and tyrosine. This variant is present in population databases (rs199476376, ExAC 0.002%). This variant has been observed in combination with another ARSA variant in several individuals affected with metachromatic leukodystrophy (MLD) (PMID: 9452102, 20339381, 28762252). This variant is also known as 1189C>T or H397Y in the literature. ClinVar contains an entry for this variant (Variation ID: 68117). This variant has been reported to affect ARSA enzyme activity in vitro (PMID: 9452102, 28762252). For these reasons, this variant has been classified as Pathogenic.
