Facioscapulohumeral muscular dystrophy is a disease of skeletal muscle, with symptoms including both facial and shoulder girdle weakness and progression to involve the pelvic girdle and extremities in the majority of cases. For most cases of FSHD, the molecular basis of the disease can be identified as a partial deletion of the D4Z4 repeat array on the end of the long arm of chromosome 4. However, in up to 5% of FSHD families there is no linkage to 4q35. These cases are designated as FSHD1B. Proteins have been identified that bind to the D4Z4 repeats of chromosome 4q35. The genes encoding D4Z4 binding proteins YY1, HMGB2, NCL, and MYOD1 were investigated as candidate genes for FSHD1B. Coding sequences and promoter region were analyzed for HMBG2 and no sequence variations were detected. For YY1, all five exons were analyzed and a polymorphism was detected in both the unaffected and affected populations. In nucleolin (NCL), several SNPs were identified, including a SNP causing the non-synonymous change P515H; however, all polymorphisms either occurred in control samples or were previously reported. A novel polymorphism was also detected in MYOD1, but did not represent a disease-specific variation. These results suggest that HMBG2, YY1, NCL, and MYOD1 are unlikely to represent the genes responsible for FSHD in these families.
