Invitae RCV000667519 SCV002242145 pathogenic Tay-Sachs disease 2024-01-29 criteria provided, single submitter clinical testing This variant results in the deletion of part of exon 1 (c.237_253+7del) of the HEXA gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in HEXA are known to be pathogenic (PMID: 1833974, 8490625). This variant is present in population databases (rs770628999, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with HEXA-related conditions. ClinVar contains an entry for this variant (Variation ID: 552290). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. For these reasons, this variant has been classified as Pathogenic.
