Objective:In the present study, we have investigated the genetic status of CTSC gene in a HMS subject, who along with her parents belonged to non-Jewish South Indian Dravidian community.Materials and Methods:Genomic deoxyribonucleic acid isolated from the peripheral blood of the subject was amplified with CTSC exon specific primers and were analyzed by direct sequencing.Results:Sequencing analysis identified Ile453Val mutation within exon 7 of CTSC gene in heterozygous condition, and two single nucleotide polymorphisms (SNPs) within intron 2 and 5 in homozygous condition.Conclusion:The present study has identified for the first time the association of Ile453Val mutation within exon 7 and the two SNPs in a subject with HMS.
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.
