Genes with pathogenic variants in several affected individuals included genes usually associated with spinocerebellar ataxia (PRKCG [n = 5], CACNA1A [n = 3], and AFG3L2 [n = 2]), spastic paraplegia (KIF1A [n = 4]), frontotemporal dementia (GRN [n = 3]), paroxysmal movement disorders (KCNMA1 [n = 3]), and others (SLC6A1 [n = 3], IFIH1 [n = 2], and NKX2‐1 [n = 2]), while only one carrier of a presumably pathogenic variant was found in the remaining 14 uncommon dystonia genes (in ATL1, CHMP2B, COL4A1, KCNJ10, KCNQ2, KCTD7, PDE10, PSEN1, SCN8A, SETX, SPAST, TBP, TCF20, and TWNK). The gene discussed is TWNK; the disease is Spastic paraplegia.
