NNSPLICE [0-1]: threshold ≥0.4 and HSF [0-100]: Human Splicing Finder, threshold ≥65. In both programs a splice site effect was considered as potentially deleterious when a variation between the native and the mutation score was more than 10%; SIFT [1-0]: scores less than 0.05 indicate substitutions are predicted as deleterious; Polyphen-2 [0-1]: scores range from 0.000 (most probably benign) to 1 (most probably damaging); Align GDGV [C0-C65]: scores range from Class C0 (less likely deleterious) to Class C65 (most likely deleterious); Mutation Taster [0-1]: from disease causing variants (p-value = 1.0) to might not be disease causing (p-value <0.99); PhyloP [-14.1 to 6.4]: from highly conserved (score >3) to moderately conserved (score 1-3) or poorly conserved (score <1); Grantham distances [0-215]: from highly different physicochemical properties and more probably damaging (score >50) to moderately (score 25-50) or poorly different and most probably tolerated (score <25); PSSM: Potential splicing site mutation.
^*Score native – mutation.
^†This variant is listed as pathogenic in NCBI ClinVar database (http://www.ncbi.nlm.nih.gov/clinvar/). Thus, it is automatically predicted to be disease-causing in Mutation Taster but real probability is shown.
