Innovative approach to genetic counseling services for the deaf population.
Genetic service providers have stressed the importance of genetic counseling that is nondirective and specific to the personal needs of consultants. Successful genetic counseling for deaf persons often requires special provisions for complex family histories, syndromic conditions, and diversity in communication methods and cultural orientation. The Gallaudet University Genetic Services Center (GSC) was established in 1984 to provide genetic education and counseling services to the deaf community. The GSC staff developed and implemented a standardized system of data collection (family and medical history), clinical evaluation by consultant clinical geneticists, and counseling in sign language. In addition to clinical services, an in-depth educational program for professionals and consumers was developed and carried out. During a 6-year period, over 220 educational presentations were made and 659 deaf persons were seen for genetic evaluation and counseling. Most of these persons were self-referred. Sign language was the preferred means of communication of more than 90% of these individuals. A genetic cause of deafness was diagnosed in over 50% of the deaf consultants and was confirmed by segregation analysis, which had results similar to those reported for other studies of students in schools for the deaf. Special materials and strategies were developed in order to provide genetic services that were sensitive to the cultural and linguistic differences of the deaf population. These included written and visual materials that contained culturally neutral terminology and training of all staff members in sign language and the culture of the deaf.
