Variant summary: PTPRC c.100+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: Three predict the variant abolishes the canonical 5' splicing donor site. Three predict the variant creates an alternate 5' splice donor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 175500 control chromosomes. To our knowledge, no occurrence of c.100+1delG in individuals affected with Severe Combined Immunodeficiency 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. -
