The Southwest of Scotland Structural Chromosomal Abnormalities Database: an assessment of its contribution to genetic counselling in affected families.
OBJECTIVE
To assess the effect of establishing a genetic database on the provision of genetic counselling to individuals and families with structural chromosomal abnormalities.


METHODS
For the four year period 1997-2000, we compared all cytogenetics laboratory records with entries on the database to determine its completeness. We assessed the extent to which families had been followed up, compared these findings with a previous four year period (1977-1980) and sought to discover why some families were not followed up.


RESULTS
Of 215 probands identified during 1997-2000, 19 (9%) were not recorded on the register. Approximately one third of families were followed up completely, one third were partially followed up and one third had had no follow-up, for a variety of reasons. In this last group, there was evidence that some had received inadequate or incorrect genetic advice. There was no evidence that the database improved follow-up in families with structural chromosome abnormalities. Over 20 years, there has been a downward trend in the proportion of cases referred to the genetic clinic.


CONCLUSIONS
Our register can be used to monitor trends in clinical practice but has had no direct effect on the service provided to patients and their families.
