Extractions: Genetics - Some Facts Chromosomal disorders affect about 7 of 1000 live-born infants and account for about half of all spontaneous first-trimester abortions. Some genetic defects affect whole chromosomes or segments of chromosomes. As in case of Downs syndrome three copies of chromosome 21 are present and no individual gene is abnormal. Chromosomal disorders can involve duplication, loss, breakage, or rearrangement of chromosomal material. Artificial chromosomes were created in yeast in the early 1980s, and the first artificial human chromosomes were created in the same medium in 1997. Medical applications of the artificial human chromosomes may include their use as vectors for moving therapeutic genes into cells to treat such diseases as sickle-cell anemia, hemophilia, and immune deficiencies. Multifactorial disorders - In these there is no single error in genetic information but a combination of small variations that together can produce or predispose an individual to a serious problem. Such disorders run in families. Environmental influences, diet and other lifestyle factors predispose the person to such disorders like - Coronary artery disease and diabetes mellitus.

A person's mental abilities and natural talents are affected by heredity. Many diseases (or susceptibility to acquire a disease) are also determined by genes. The terms anomaly, abnormality, disorder, defect, disease, and syndrome are not used consistently, and do not have precise definitions. In chromosomal disorders, the defect is due not to a single gene, but to an excess or deficiency of the genes contained in a whole chromosome or chromosome segment.

http://www.gpnotebook.co.uk/cache/-1785069534.htm

Extractions: chromosomal disorders If mutations of genetic material are large enough to be seen under the light microscope, they are called chromosomal aberrations. They can be divided into structural and numerical abnormalities. The smallest visible alteration to a chromosome that is visible is approximately four million base pairs. Chromosomal disorders are very common, affecting 7.5% of all conceptions, yet, due to spontaneous miscarriage, their livebirth frequency is only 0.6%. Hence, amongst spontaneous early miscarriages, 60% have a chromosomal abnormality, usually that of trisomy, 45,X, or triploidy. Disorders of this kind may result from germ cell mutations in the parent that have been passed on to sex chromosomes or autosomes in the affected individual. Alternatively, chromosomal aberrations may arise out of somatic mutation in the generation affected. Generally, autosomal chromosomal disruptions are more severe than sex chromosome abnormalities. Similarly, deletions are more deliterious than duplications.

Extractions: Genome 2000 Application of Microsatellite Genotyping in Chromosomal Disorders Ming-yi ChunG Department of Medical Research and Education, Veterans General Hospital-Taipei, Taiwan, R.O.C. Microsatellite markers, a.k.a. short tandem repeats (STR) or simple tandem repeats, contain repetitive sequence composed of di-, tri-, or tetra-nucleotides. The number of repeats may vary from one person to another, i.e. polymorphic, and follow Mendelian inheritance. Due to their high informativeness and easy accessibility, these markers have been widely applied in various field of genetic research. Chromosomal disorders can be structural or numerical. Unbalanced chromosome disorders can be further investigated to delineate the nature of the defect, in terms of imprinting/parental origin and size of chromosome involved in the defect by using microsatellite genotyping. Chromosome 22q11 microdeletion syndrome and trisomy 21 will be discussed as examples.

Extractions: Chromosomal aberrations in children with suspected genetic disorders Volume 3, Issue 1, 1997, Page 114-122 Mohamed M. Mokhtar ABSTRACT Karyotyping was done in 137 children suspected of having chromosomal abnormalities such as genetically uncertain syndromes, multiple congenital anomalies, short stature, dysmorphic features, unclassified mental retardation and Down syndrome. A total of 53 (38.7%) had an abnormal karyotype: trisomy 21 (36; 26.3%), trisomy 18 (3; 2.2%), trisomy 13 (1; 0.7%), partial autosomal aneuploidy (5; 3.6%), pericentric inversion of chromosome 9 (2; 1.5%), marker chromosome (2; 1.5%) and sex chromosome aberrations (4; 2.9%). All of them showed phenotypic-cytogenetic heterogeneity. These findings suggest that cytogenetic analysis is useful in the investigation of children with genetic disorders of unknown origin to confirm clinical diagnosis and to allow for proper genetic counselling. Les aberrations chromosomiques chez les enfants suspects de troubles génétiques Resume Un cariotype a été réalisé chez 137 enfants suspects d'anomalies chromosomiques telles les syndromes génétiquement incertains, les anomalies congénitales multiples, le retard statural, les traits de dysmorphie, l'arriération mentale non classifiée et le syndrome de Down. Au total, 53 enfants avaient un cariotype anormal: trisomie 21 (36; 26,3%), trisomie 18 (3; 2,2%), trisomie 13 (1; 0,7%), hétéroploïdie autosomique partielle (5; 3,6%), inversion péricentrique du chromosome 9 (2; 1,5%), marqueur chromosomique (2; 1,5%) et aberrations des chromosomes sexuels (4; 2,9%). Tous présentaient une hétérogénéité phénotypique et cytogénétique. Ces résultats laissent penser que l'analyse cytogénétique est utile dans les investigations réalisées chez les enfants ayant des troubles génétiques d'origine inconnue afin de confirmer le diagnostic clinique et de permettre le conseil génétique approprié.

Extractions: Epidemiology of congenital abnormalities in Bahrain Volume 1, Issue 2, 1995, Page 248-252 Sheikha Salim Al Arrayed This study was carried out in order to find out the incidence of congenital anomalies in Bahrain. Statistics of the Bahraini Ministry of Health for 11 years from 1980 to 1990 were studied. The overall incidence rate of congenital anomalies in Bahrain was found to be 2.7% of live births. Each anomaly was studied separately and compared with the incidence in other countries, whenever possible. It was found that anomalies of the musculoskeletal system have the highest incidence (2.28 per 1000), followed by the genitourinary system (2.13 per 1000), while the incidence of chromosomal disorders was 0.9 per 1000. Epidémiologie des anomalies congénitales à Bahreïn Cette étude a été réalisée afin de déterminer l'incidence des anomalies congénitales à Bahreïn. Les statistiques produites par le Ministère de la Santé de Bahreïn sur une période de 11 ans de 1980 à 1990 ont été examinées. On a trouvé que le taux global de l'incidence des anomalies congénitales à Bahreïn s'élevait à 2,7% des naissances vivantes. Chaque anomalie a été étudiée séparément et son incidence a été comparée avec celle d'autres pays, chaque fois que possible. Cette étude a montré que l'incidence la plus élevée était celle concernant les anomalies du système ostéo-articulaire et musculaire (2,28 pour 1000) suivie par l'incidence des anomalies des organes génitaux et de l'appareil urinaire (2,13 pour 1000), tandis que l'incidence des anomalies chromosomiques s'élevait à 0,9 pour 1000.

PEDIGREES AND GENOGRAMS Through the study of human pedigrees, it was discovered that different diseases have different characteristic patterns of inheritance. Genograms, in addition to medical information, provide qualitative information about the relationships and functioning of a family. Constructing and analyzing pedigrees and genograms is an important part of medical genetics. All health professionals should feel comfortable utilizing and applying pedigrees and genograms to elucidate a family history, assess the recurrence risk for a genetic disorder, and gain an understanding of the family context in which their patients live. Patterns of inheritance are grouped into several categories:
