ABSTRACT

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.
