Exam 5: Genetics: Basis for Development and Disorders

Changes within genes can produce proteins that don't work normally or don't work at all,which may result in disease or disorder.

Each time a gene is passed from one generation to the next,some alterations occur.

The Gene Expression Nervous System Atlas GENSAT)helps investigators understand which genes are critical in the nervous system and how they function.

Genetics

Gene expression refers to the passing on of traits from parents to children.

Chromosome 1 is the largest human chromosome but has the fewest number of genes.

Phenotypes refer to

Syndrome

Recessive inheritance

Genes

Genes are composed of DNA and are found on specific locations of the chromosomes.

Research linking genetics with communication disorders include identifying genetic markers for speech delay,laryngeal paralysis,and autism.

Birth defects

Consultation with a genetic counselor may be helpful for speech-language pathologists and audiologists if their client has

Constructing pedigrees for a family that has a child with a genetic disorder is one clinical service provided by audiologists and speech-language pathologists.

Speech-language pathologists and audiologists may consult with genetic counselors to assist families with preventing some communication disorders.

Slight variations in our genomes that are responsible for our individual differences and predisposition to disease and disorder are called

Dominant inheritance

Specific genes have been associated with deafness and Alzheimer's disease.
