Ten members of a 3‐generation pedigree with 7 showing Tourette syndrome/chronic tic phenotype (TS‐CTD) were evaluated with whole exome sequencing. We identified 3 novel, nonsynonymous single nucleotide variants in the MRPL3, DNAJC13 , and OFCC1 genes that segregated with chronic tic phenotype. These variants were not present in 100 control subjects or in dbSNP/1000 Genomes databases. A novel variant in the 5′ untranslated region of the OFCC1 gene was found in 2 TS‐CTD patients from a different pedigree. Further studies will clarify the importance of variants in MRPL3, DNAJC13 , and OFCC1 genes in TS. Ann Neurol 2011;69:901–904
