Abstract
Background: Allgrove syndrome is autosomal recessive disorder, the gene involved in this syndrome is known as ALADIN located close to type 2 keratin gene cluster on chromosome 12q13 whose function is to control the nucleocytoplasmic trafficking and also affects the nuclear pore complexes. Mutation in this gene cause triple A syndrome. The aim of research was to analyze the mutational changes in ALADIN gene, formation of 3D Structure of normal and mutated protein and differentiation of normal and mutated protein.
Methods: Genotyping by using tetra arm PCR and Sequence analyses of coding region of ALADIN gene was done in two families having affected children with Allgrove’s syndrome.
Results: Point mutation in exon 1 and alteration in 3D structure of protein was observed by using VMD (Visual molecular dynamics) that shows truncation, absence of few amino acid and structural modification of proteins which alters in transportation ability.
Conclusion: It is concluded from the study that proper structure and function of NPC (nuclear pore complex) binding protein is necessary in normal body function and if any mutation is present in ALADIN gene it can cause symptoms of rare Allgrove’s syndrome.
