Extractions: Surprisingly, it is only in the last 50 years that we have begun to understand the nature of the biological events which determine our sex, (and for that matter, why we bother with sex at all and why two sexes are better than three or more). It is not so long ago that women were blamed if they failed to produce a son for their husband and clearly it was thought that the power of sex determination lay within the body of the woman. During this century the chromosomal basis of human sex determination has been demonstrated and in the last few years some of the genes responsible have been identified. The sexual identity of an individual is determined at several levels, chromosomal sex, gonadal sex, somatic sex and sexual orientation. The chromosomal basis of sex determination in humans was recognized when metaphase chromosomes from dividing male and female cells could be studied and counted. The normal karyotype contains 46 chromosomes including either two X chromosomes (46XX, females) or one X chromosome and one Y chromosome (46XY, males). Individuals with or karyotypes are female, individuals with

Extractions: Click here for Gene Reviews Clinical Summary for PWS Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are clinically distinct, complex disorders, and genetically heterogeneous. Both PWS and AS have been found to result from a deletion in the same area of chromosome 15 (15q11-q13). A deletion in the paternally contributed chromosome will result in PWS, while a deletion in the maternally contributed chromosome will result in AS. For PWS, greater than 70% of cases result from the deletion on chromosome 15 inherited from the father, while 25% occur due to maternal uniparental disomy (UPD). Approximately 5% of PWS cases have an abnormality in the imprinting process (resulting in nonexpression of the paternal genes in the PWS critical region). For AS, greater than 70% of cases result from the deletion on chromosome 15 inherited from the mother, while 3-5% occur due to paternal uniparental disomy (UPD). Another 2-3% of AS patients have an abnormality in the imprinting process. The remaining 25% in this group are hypothesized to have AS on the basis of a single gene mutation whose genetic locus is unknown. In order to determine the likelihood of recurrence for genetic counseling purposes, FISH, and methylation analysis with or without chromosome analysis will be necessary. Emory Genetics follows the recommendations of a joint American College of Medical Genetics/American Society of Human Genetics Test and Technology Transfer Committee, for clinically valid identification and diagnosis of PWS and AS individuals published in 1996*:

Full information regarding the FISH assay requested must be indicated on the requisition form. Please call the Cytogenetics Lab at (314) 454-8101 for any questions about FISH. Cultured peripheral blood lymphocytes are processed as for a routine cytogenetic study and analyzed by the investigative method FISH. The D15S10 cosmid (Vysis, Inc.) and a control probe, D15Z1 (Vysis, Inc.) which tag chromosomes 15 are hybridized to metaphase chromosomes. The D15S10 probe has been found deleted in a high proportion of patients with Prader Willi syndrome, Angelman syndrome or in other disorders with similar phenotypes. Although the probe is from the smallest region of overlap of the deletions in these patients, it is not known to be the specific gene which causes the phenotype.

Extractions: What is uniparental disomy? Normally, we inherit one copy of each chromosome pair from our biological mother, and the other copy of the chromosome pair from our biological father. Uniparental disomy refers to the situation in which two copies of a chromosome come from the same parent, instead of one copy coming from the mother and one copy coming from the father. Angelman syndrome and Prader-Willi syndrome are examples of disorders caused by uniparental disomy. What is Angelman syndrome (AS)? People with Angelman syndrome (AS) have mental retardation, severe speech problems, stiff arm movements, and a stiff, uncoordinated walk. They may have seizures and often have inappropriate outbursts of laughter. Angelman syndrome results when a baby inherits both copies of chromosome #15 from the father (rather than one from the mother and one from the father). What is Prader-Willi syndrome (PWS)?
