CAG repeat length variation in sperm from a patient with Kennedy's disease.

Human molecular genetics - 1 Feb 1995

Zhang L, Fischbeck K H, Arnheim N

Abstract excerpt

Using a modified sperm typing protocol, the mutation frequency of the CAG repeat region at the androgen receptor locus has been measured using a rare semen sample from an individual with spinal and bulbar muscular atrophy (SBMA). Among 258 X chromosome-containing sperm, 19% had a repeat number equal to the donor's somatic DNA (47 repeats), 66% were expansions and 15% were contractions. The average expansion was...
