KIF1A and Spastic paraplegia: 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).
