Description

Frameshift deletion of 4:1101955 resulting in the addition of VAYSLMVAHFPMSFVSVLWSWPIMGSAHVTYHVNYVLVTVVCLKYFQDIMRLVVLKLVLLAGPNLKWPLPRL after leucine 182 of the sv PA, PC, PD, PF, PG and PH isoforms and premature truncation after these novel amino acids. The mutation does not affect the sv PI isoform.
