Following criteria are met: 0102 - Loss-of-function is a known mechanism of disease for this gene. (N) 0107 - This gene is known to be associated with autosomal dominant disease. (N) 0211 - Canonical splice site variant without proven consequence on splicing (no functional evidence available) (intron 13 of 18). (P) 0251 - Variant is heterozygous. (N) 0301 - Variant is absent from gnomAD. (P) 0505 - Abnormal splicing is predicted by in silico tools and affected nucleotide is highly conserved. (P) 0702 - Comparable variants have strong previous evidence for pathogenicity. Two alternative changes at the same nucleotide, to thymine and adenine, have previously been reported as pathogenic (ClinVar, OMIM). The latter splice variant was also shown to result in the skipping of exon 13 and a subsequent frameshift (PMID: 21237447). (P) 0807 - Variant has not previously been reported in a clinical context. (N) 0905 - No segregation evidence has been identified for this variant. (N) 1007 - No published functional evidence has been identified for this variant. (N) 1208 - Inheritance information for this variant is not currently available. (N) Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign
