Neuronal ceroid lipofuscinosis 5 Pathogenic:2

Variant summary: CLN5 c.321-2A>G 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: Five predict the variant abolishes a 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant was absent in 245446 control chromosomes (gnomAD). To our knowledge, no occurrence of c.321-2A>G 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. -
