inv(5)(p13q13) in a four generation pedigree.
A 4 1/2 years old boy was found to have hypoplasia of the pectoralis major right muscle and a karyotype 46,XY,inv(5)(p13q13)mat. This inversion, probably independent of the boy's malformation, was present in at least four generations and it seems neither to impair fertility nor to yield viable recombinants.
