Locus OPDM4 RILPL1

Benign alleles have been documented to have 6-16 repeats⁴, while pathogenic repeats range from 120 to 197 repeats; there is no apparent relationship between allele size and age of onset^4,2. Intermediate alleles may be associated with incomplete penetrance, or milder phenotypes². AGG, TGG, and CGT interruptions observed^2,3.
