45 Of interest were four compound heterozygotes with G1961E change in one allele (P6, P11, P12, P15): those with frameshift mutations in the second allele (2005delAT or 4531insC) showed less degeneration at older ages (55 and 29, respectively) than those with point mutations (R2149L or E1122K) at younger ages (48 and 19, respectively).
