A CCG expansion in ABCD3 causes oculopharyngodistal myopathy in individuals of European ancestry

In this study we describe the identification of CCG expansions in ABCD3 in affected individuals across eight unrelated OPDM families of European ancestry. In two large Australian OPDM families, using a combination of linkage studies, short-read WGS and targeted ONT sequencing, we identified CCG expansions in the 5’UTR of ABCD3. Independently, the ABCD3 CCG expansion was identified through the 100,000 Genomics England Genome Project in three individuals from two unrelated UK families diagnosed with OPDM.
