Description

Published functional studies demonstrate a damaging effect, specifically, I181S results in approximately 5% residual arylsulfatase A activity, compared to wildtype (Fluharty et al., 1991); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 12081727, 31684987, 20301309, 9600244, 26462614, 28762252, 26890752, 18786133, 21896413, 30083785, 31186049, 31262576, 18693274, 31980526, 1684088, 9096767, 32632536, 31589614)

Description

This variant is one of the most common variants associated with autosomal recessive metachromatic leukodystrophy in the European population (PMID 15952986, 9096767), therefore The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant appears to segregate with disease in at least one family, however, the available information does not rule out segregation due to chance. This variant is also referred to as c.536T>G (p.Ile179Ser) in published literature. Assessment of experimental evidence suggests this variant results in abnormal protein function. This variant was shown to significantly reduce arylsulfatase A activity (PMID 1684088). In multiple individuals, this variant has been seen with a single recessive pathogenic variant in the same gene, suggesting this variant may also be pathogenic. Computational tools predict that this variant is damaging.
