RCV000670737 | SCV001360437 | pathogenic | Metachromatic leukodystrophy | 2019-05-13 | criteria provided, single submitter | clinical testing | Variant summary: ARSA c.109_116delGACCTGGG (p.Asp37LeufsX36) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory (eg. c.304delC(p.Leu102fsX6); c.960G>A(p.Trp320X)). The variant allele was found at a frequency of 1.2e-05 in 165594 control chromosomes (gnomAD) and has been reported in the literature in individuals affected with Metachromatic Leukodystrophy (Draghia_1997, Virgens_2015). Three of these patients had infantile metachromatic leukodystrophy. These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic. |
Invitae | RCV000670737 | SCV001419379 | pathogenic | Metachromatic leukodystrophy | 2023-06-29 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 555003). This variant is also known as 103del8bp. This premature translational stop signal has been observed in individual(s) with metachromatic leukodystrophy (PMID: 9090526). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change creates a premature translational stop signal (p.Asp37Leufs*36) in the ARSA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ARSA are known to be pathogenic (PMID: 8962139, 10477432). |
