An outline for PowerPoint slides on "down syndrome" is given as follows:

Slide 1. It will be about the disease.

What is the down syndrome?

=>Down syndrome is a genetic condition in which there are 47 chromosomes (an extra than usual 46).

=>Typically associated with delay in cognitive ability leading to mental retardness, physical growth and unique facial characteristics.

=>IQ of affected person is around 50 as compared to normal value of 100.

Slide 2. It will be about the cause of disease.

=> It Occurs due to an extra 21st chromosome.

=> Three major causes:

1. Trisomy 21 - three copies of 21st chromosome.

2. Mosaic down syndrome - due to abnormal cell division after fertilization.

3. Translocation down syndrome - part of 21st chromosome is aatched with other chromosome during or before conception.

Slide 3. Signs and symptoms of the disease.

Small head

Upward slanting eyes

Flattened nose

Small mouth with with protruding tongue

Weak floppy muscles

Rounded cheeks

Wide short hand with short fingers.

=> Other complications include heart defects, dementia, thyroid disease, infectious disease and leukaemia.

Slide 4. Risk factors of disease.

=> Advance maternal aging = the chance of having down syndrome babies increases with age.

=> Parents carrier of the disease have high chance of genetic translocation to offsprings.

Slide 5. Statistics about the disease.

Risk of 1 baby in 800 babies.

3,40,000 individuals affected in US.

88% from mother, 8% from father, rest from cell division errors.

Slide 6. Diagnosis

=> Karyotype analysis

=> Ultrasound during pregnancy - two step screening tests during 11the and 13th week.

=> tests include

Amniocentesis

Clorionic villius sampling

Percutaneous umbilical blood sampling

Slide 7. Treatment and therapies

=> Medicines usually target the defects and symptoms.

=> Currently, there is no medical cure for the disease.

=> Surgery is another alternative to cope with the severe complications due to disease.

=> Physical therapy for muscle related defects.

=> Speech therapy for vocal defects.

=> Occupational therapy for developing skills in the affected child.

=> Music therapy for supporting the development and confidence.

=> Counselling of parents and care takers.

1. Gillespie syndrome (GS) is a rare genetic disorder. The disorder is characterized by having part of the iris missing, ataxia, and, in most cases, intellectual disability. It is termed as a heterogenous disorder because it can be inherited either through an autosomal dominant pattern or through an autosomal recessive pattern. Two parents are heterozygous for GS. A. Assuming that the condition is following an autosomal dominant pattern, what are the ratios or percentages of the genotypes AND phenotypes for...

1. An individual with classic symptoms of Down syndrome is found to have 46 chromosomes. How can this be? This is possible if the individual has an extra chromosome 21 but has only one copy of chromosome 1. This is not possible. It is possible if she or he carries a chromosome translocation, such as 14/21. It is possible if she or he carries a chromosome inversion.
