PARL and leprosy: To identify whether there are any other rare (allele frequency < 1%) or common variants that would confer risk to leprosy, we performed targeted gene sequencing (including the flanking region of the gene) for PARL, PINK1 and PARK2 in 80 leprosy patients from the Wenshan Prefecture, Yunnan Province, and compared to the CHB data in 1000 Genomes dataset37.
