  1. Phenotype is displayed in the PT columns (M – “mild”; S – “severe”, where “mild” is defined as homozygous or heterozygous for class IV-V mutations and “severe” as homozygous for class I-III mutations). cDNA variant names according to HGVS nomenclature are given below the table for each variant.
