Targeted next-generation sequencing identifies novel variants in candidate genes for Parkinson’s disease in Black South African and Nigerian patients

Table 1 Characteristics of the 47 Parkinson’s disease patients

Characteristic	Black South African N = 33	Nigerian N = 14
Sex, male, n (%)	18 (54)	11 (78)
Average age-at-onset ± SD (range), years	48 ± 8 (30–59)	63 ± 13 (36–80)
Average age at recruitment ± SD (range), years	55 ± 11 (35–78)	67 ± 11 (42–81)
Positive family history of PD, n (%)	2^a (6)	0

^a Individuals s43_059 and s94_069 have a possible Mendelian inheritance pattern for PD
