We describe 3 young children with Hallermann–Streiff syndrome, 2 with typical manifestations and 1 with the facial changes without the eye abnormalities but with a cleft palate and with complete syndactyly of fingers IV and V. The latter case represents overlap of the Hallermann–Streiff syndrome and oculodentodigital dysplasia. “Dwarfism” as a possible clinical risk marker of mental retardation is discussed. As cause, a mendelian autosomal dominant mutation seems most probable. 相似文献

Knowledge of mycobacterial glycolipid antigens and the study of their specificity have resulted in their utilization as species markers. We describe a thin-layer chromatography method which could serve as a useful adjunct for the identification of Mycobacterium tuberculosis, M. bovis BCG, M. kansasii, M. gastri and M. marinum. 相似文献

Convincing evidence for a genetic component in the etiology of affective disorders (AD), including bipolar affective disorder (BPAD) and unipolar affective disorder (UPAD), is supported by traditional and molecular genetic studies. Most arguments lead to the complex inheritance hypothesis, suggesting that the mode of inheritance is probably not Mendelian but most likely oligogenic (or polygenic) and that the contribution of genes could be moderate or weak. The purpose of the present European multicenter study (13 centers) was to test the potential role in BPAD and UPAD of two candidate dopaminergic markers, DRD2 and DRD3, using a case‐control association design. The following samples were analyzed for DRD2: 358 BPAD/358 control (C) and 133 UPAD/ 133 C subjects, and for DRD3: 325 BPAD/ 325 C and 136 UPAD/136 C subjects. Patients and controls were individually matched for sex, age ( ± five years) and geographical origin. Evidence for significant association between BPAD and DRD2 emerged, with an over‐representation of genotype 5‐5 (P = 0.004) and allele 5 (P = 0.002) in BPAD cases compared to controls. No association was found for DRD2 in UPAD, and for DRD3 neither in BPAD or UPAD. Our results suggest that the DRD2 microsatellite may be in linkage disequilibrium with a nearby genetic variant involved in the susceptibility to BPAD. Our large European sample allowed for replicating of some previous reported positive findings obtained in other study populations. © 2002 Wiley‐Liss, Inc. 相似文献
