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). This evidence concerns the gene AFG3L2 and frontotemporal dementia.
