Heterozygous Ile453Val codon mutation in exon 7, homozygous single nucleotide polymorphisms in intron 2 and 5 of cathepsin C are associated with Haim-Munk syndrome.

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.
