Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV003155764 SCV003844735 likely pathogenic Neuronal ceroid lipofuscinosis 2023-02-14 criteria provided, single submitter clinical testing Variant summary: The variant identified by MLPA or other technology involves the deletion of exons 5-7 in the MFSD8 gene. A presumed nomenclature of c.(198+1_199-1)_(698+1_699-1)del has been designated for the purposes of this classification. Although exact breakpoints of this deletion are not known, it is expected to result in a frameshift in the MFSD8 gene, a known mechanism of disease. The variant was absent in 21690 control chromosomes (gnomAD Structural Variants dataset). To our knowledge, no occurrence of c.(198+1_199-1)_(698+1_699-1)del in individuals affected with Neuronal Ceroid-Lipofuscinosis (Batten Disease) and no experimental evidence demonstrating its impact on protein function have 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 likely pathogenic.
