GENETIC DIAGNOSIS BY WHOLE

EXOME CAPTURE AND MASSIVELY

PARALLEL DNA SEQUENCING:

CHOI ET AL. PNAS: 2009

• DNA samples were collected and prepared for sequencing

• Identified homozygous missense D652N mutation at a position in

SLC26A3 gene that is known to be associated with congenital chloride

diarrheas.

STAS Cl/HCO3

exchanger

First report on making a clinical diagnosis using, whole exome capture and next-generation high throughput DNA sequencing

• 5 month child

presented with failure

to thrive & dehydration

• Treatments for kidney

disease failed

CLINICAL USES OF GENOME

SEQUENCING

Cancer: sequence tumors to guide initial Rx and Rx of recurrent disease

Inherited susceptibilities

Solve clinical mysteries

Newborn screening?

Genome sequencing at birth?

YCGA is carrying out clinical diagnostic work in collaboration with Dr. Allen Bale

Over 700 exomes are analyzed for various disorders

2014 marks the first time when demand for genetic counselors outstripped supply in the

United States. The quick spread of genetic testing is accelerating this need and creating

pressure for scalable solutions.

GENETIC TESTING: COUNSELORS

WIDELY NEEDED

WHAT IS GENETIC COUNSELING?

“Genetic counseling is the process of helping people

understand and adapt to the medical, psychological,

and familial implications of genetic contribution to

disease. This process integrates the following:

Interpretation of family and medical histories to assess

the chance of disease occurrence or recurrence.

Education about inheritance, testing, management,

prevention, resources and research. Counseling to

promote informed choices and adaptation to the risk or

condition.”

National Society of Genetic Counselors’ Definition Task Force

J. Genet Couns 2006,15, 77-83

CURRENT EXAMPLES OF REMOTE GENETIC

COUNSELING

BUILDING A SCALABLE SOLUTION

Research on the use of an interactive computer program prior to genetic counseling showed the combination to be more effective than

standard genetic counseling for increasing knowledge of genetic testing

Resulted in significantly shorter counseling sessions

Shifted the focus of counseling session away from basic education toward personal risk and decision-making

testing for breast cancer susceptibility. Journal of the American Medical Association, 292(4), 442-452.
