Congenital glaucoma in a child with partial 1q duplication and 9p deletion.

A case of partial duplication of chromosome 1 (1q41-qter) and partial deletion of chromosome 9 (9p24-pter) with infantile congenital glaucoma is reported. The histopathology of the eyes is described. The clinical findings ascribed to trisomy 1q and partial monosomy 9p are summarized and compared to this case. As this is the second report of a patient with monosomy 9p24-pter and congenital glaucoma, it may indicate localization of a gene involved in congenital glaucoma in this region of the human genome.

Partial trisomy 10q: a recognizable syndrome.

Five cases from two nonrelated families with partial trisomy 10q due to a reciprocal translocation t(10;17)(q25;p13) and t(10;11)(q24;q23), respectively, are reported. The phenotypic findings are compared with those of 17 previously published cases; the clinical data justify the conclusion that cases with trisomy 10q show a specific syndrome of mental retardation and malformation characterized by psychomotor retardation, growth retardation, hypotonia, high forehead, flat face, fine and arched eyebrows, antimongoloid slant of the eyes, narrow palpebral fissures, hypertelorism, short nose, bow-shaped mouth, short neck (kypho)scoliosis, and in some cases microcephaly.

Two cases with different deletions of the long arm of chromosome 7.

Two mentally and physically retarded girls, one with an interstitial deletion 7 (pter leads to q21::q32 leads to qter), and the other with an interstitial deletion 7 (pter leads to q11::q22 leads to qter), are described. Their clinical features are compared with those of 11 earlier reported cases with a deletion 7q. The Hageman factor, the locus of which is assigned to the distal part of 7q, was in both cases within normal limits. The data available do not justify the delineation of a specific clinical syndrome.

Double translocation t(7;12),t(2;6) heterozygosity in one family. A contribution to the trisomy 12p syndrome.

Double translocation heterozygosity t(2;6),t(7;12) in three generations of a Dutch family is described: the segregation of a double translocation in more than one generation has not been previously published. The index case was a 16-year-old mentally retarded boy with partial trisomy 12p who showed several dysmorphic features such as high prominent forehead, flat face, flat and short nose bridge, short nose, dysplastic ears, prominent lower lip, and several skeletal abnormalities. Based on the findings in this patient and those in nine other cases, the existence of a specific trisomy 12p syndrome is postulated.

Partial trisomy 6p due to familial translocation t(6;20)(p21;p13). A new syndrome?

Cytogenetic findings in a case of partial trisomy 6p due to a translocation t(6;20)(p21;p13) and eleven balanced translocation heterozygotes are described. The clinical data of the proposita are compared with those of five other published cases. A partial trisomy 6p syndrome is postulated, characterized by: low birth weight, psychomotor retardation, craniofacial abnormalities (such as high prominent forehead, large fontanel, wide sagittal suture, blepharoptosis, low-set and/or malformed ears), congenital heart malformation, small kidneys, and proteinuria. Linkage studies have shown that the breakpoint in chromosome 6 involved in this translocation is close to the HLA gene cluster.

Identical giemsa banding patterns of two macaca species: Macaca mulatta and M. fascicularis. A densitometric study.

Karyotypes of Macaca mulatta and M. fascicularis (2n equals 42) were compared using the Giemsa banding pattern technique. No differences between the chromosomes of both Macaca species were found with conventional staining methods. In the literature the occurrence of fertile hybrids is used as an argument in favor of conspecificity. The banding patterns were evaluated by comparison of their density distribution curves. Our data indicated no significant differences between the two Macaca species.
