There is close co-operation between the laboratory and clinical services and the centre prides itself on providing an integrated clinical genetics service.

The centre works to the highest of standards to ensure that the best possible service is offered to patients and their families.

Both the cytogenetic and molecular genetic laboratories are CPA accredited (Reference numbers 1773 & 2148 respectively).

Description of service

Clinical genetics service

The clinical geneticists and genetic counsellors provide an outpatient-based diagnostic and counselling service at Northwick Park Hospital and numerous outreach clinics.

Individuals with a genetic disorder, or relatives at risk of a genetic disorder, are seen and advised of the causes and consequences of the disorder, the risk of developing or transmitting it and the options available to them such as tests, treatment or prevention.

Clinics are also held for those where there is a familial history of cancer.

Clinical cytogenetics

Clinical cytogenetics is concerned with the analysis of the chromosome complement of an individual to determine whether there is a change from the expected number of 46 chromosomes (e.g. as in Downs Syndrome) or whether there is a microscopically detectable change in chromosome structure that could be of pathological significance.

The laboratory provides an interpretative reporting service to users.

Clinical molecular genetics

A wide variety of molecular biology techniques are applied to investigate individual genes that are associated with a range of specific genetic disorders.

In most cases the approach is to test for the presence of a specific defect (“mutation”) within the gene in question. In some cases (i.e. when the specific mutation can not be detected), analysis can be performed by tracking patterns of DNA markers within a family.
