Adult onset hereditary hemochromatosis is associated with a novel recurrent Hemojuvelin (HJV) gene mutation in north Indians.

Hereditary hemochromatosis (HH) is a rare disorder in Indians and is not associated with the common mutation Cys282Tyr in HFE gene found in Caucasians. Non-HFE HH can be associated with mutations in HJV, HAMP, TFR2 and SLC40A1 genes. Nineteen unrelated north Indian HH patients were detected after screening 258 chronic liver disease patients on the basis of increased transferrin saturation, ferritin levels >1000 ng/L and siderosis by Perl's stain on liver biopsy wherever available.

Genotype-phenotype correlation of SMN locus genes in spinal muscular atrophy patients from India.

Spinal muscular atrophy has been classified into four groups based on the age of onset and clinical severity of the disease. Homozygous deletion in SMN1 gene causes the disease but the clinical severity may be modified by copy number of homologous gene SMN2 as well as the extent of deletion at SMN locus. In the view of scarcity of genotype and phenotype correlation data from India, this study has been undertaken to determine that correlation in SMA patients by using the SMN and NAIP genes and two polymorphic markers C212 and C272 located in this region.
