title: [A further example of chromosome 18q-associated with IgA deficiency in serum and saliva (author's transl)].
abstract: In a 3 1/2 years old boy with congenital malformations, statomotoric and mental retardation and immunological defects the chromosomal aberation 46,XY, 18q- was found. The result of the G-band analysis was 46,XY, del (18) (pter yields q11::q21 leads q ter) or 46,XY, del (18) (pter leads q21). The structural genes for the systems Gm, PGM-1 and HL-A presumably are not localized on the deleted chromosomal segment.
