With the increasing number of cancer cases worldwide, genetic testing for familiar cancers seems inevitable, yet little is known on population interest and the monetary value for cancer genetic risk information. The current study aimed to determine the willingness to undergo and pay for cancer genetic testing among the Malaysian population. A self-administered questionnaire was distributed to cancer patients and their family members in the oncology and daycare units in several government hospitals. Of 641 respondents (354 patients, 287 family members), 267 (41.7%) were willing to undergo cancer genetic testing. The median that respondents were willing to pay was USD 48.31 (MYR 200.00) IQR USD 96.91 (MYR 400), while 143 (22.3%) respondents were willing to pay a shared cost with the insurance company. Regression analysis identified independent positive predictors of willingness to pay as respondent’s status as a family member, high education level, and willingness to undergo cancer genetic testing in general, while in patients, female gender and high level of education were identified as independent positive predictors. Generally, the population needs more information to undergo and pay for cancer genetic testing. This will increase the utilization of the services offered, and with cost-sharing practices with the provider, it can be implemented population-wide.
Alpha-thalassemia mental retardation syndrome is an X-linked mental retardation (MR) syndrome characterized by a recognizable facial appearance, infantile hypotonia and cryptorchidism. Although the presence of alpha-thalassemia facilitates the diagnosis, its absence does not exclude the diagnosis of this rare syndrome. We describe two siblings who presented with facial dysmorphism, MR and a four-generation pedigree that revealed an X-linked recessive inheritance pattern. Their red blood cell indices were within the normal range; however, hemoglobin H inclusions were detected following cresyl blue staining on their peripheral blood film. Mutational analysis revealed a point mutation C7156T that is predicted to have caused a premature termination within the alpha-thalassemia MR syndrome gene in both siblings. Confirmation of this mutation has facilitated the process of genetic counseling, carrier testing and prenatal diagnosis amongst female relatives in this family.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
