Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001269103 SCV001448344 likely pathogenic Multiple sulfatase deficiency 2023-09-29 criteria provided, single submitter clinical testing Variant summary: SUMF1 c.270+1delG is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. Several computational tools predict a significant impact on normal splicing: One predict the variant abolishes the 5' canonical splicing donor site. One predict the variant weakens the 5' canonical splicing donor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 228506 control chromosomes. To our knowledge, no occurrence of c.270+1delG in individuals affected with Multiple Sulfatase Deficiency and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic.
