Comparing the “stroke” group and the rest of the SCA patients, we found frequency differences in ITGA2B [MIM: 607759], CALCA [MIM: 114130], LTC4S [MIM: 246530], EMILIN1 [MIM: 130660], SERPINC1, NPHS1 [MIM: 602716], ACD [MIM: 609377], and USP37 (P = 3.46 × 10−7, 5.36 × 10−7, 3.96 × 10−6, 4.96 × 10−6, 6.22 × 10−6, 5.85 × 10−6, 1.86 × 10−5, and 1.48 × 10−5, respectively; Figure S8). This evidence concerns the gene LTC4S and autosomal dominant cerebellar ataxia.
