313700.0014; SPINAL AND BULBAR MUSCULAR ATROPHY, X-LINKED |
| Identified Mutation |
(CAG)n EXPANSION; Studying 35 unrelated patients, La Spada et al. (1991) found an increased size of a polymorphic tandem CAG repeat (polyglutamine tract) in the coding region of the androgen receptor gene. These amplified repeats were found in none of 75 controls and segregated with the disease in 15 families. The association was not likely to be due to linkage disequilibrium because 11 different disease alleles were observed.

| Remarks |
Clinically affected; onset of symptoms at age 45; this subject has 51 CAG trinucleotide repeats in the first exon of the androgen receptor gene (AR)(normal range= 4-33 copies); positive family history: maternal grandfather had severe leg weakness and 3 male cousins have tested positive for SBMA (samples from family are not in repository). |
