OBJECTIVE To study the association between common AIDS restriction genes and slow disease progression among perinatally-infected children in India. METHODS ART-naïve children were identified and selected host factors including CCR5-∆32, SDF1-3'A, CCR5-59029G, HLA-B*27, B*57 were studied using allele-specific PCR-RFLP and SSPGo HLA typing kits. RESULTS Among 165 children, 10 (6%) long-term non-progressors and 8 (5%) slow progressors were identified. For comparison, 12 children with normal progression of HIV were included. The frequencies of CCR5-∆32 deletion, SDF1-3'A and CCR5-59029G did not differ significantly. HLA-B*27 and B*57 were observed only in long-term non-progressors or slow progressors, who also harbored either SDF1-3'A and/or CCR5-59029G. CONCLUSIONS There is an association between host genetic factors and slow disease progression in this population.

UI	MeSH Term	Description	Entries
D007194	India	A country in southern Asia, bordering the Arabian Sea and the Bay of Bengal, between Burma and Pakistan. The capitol is New Delhi.	Republic of India
D008297	Male		Males
D012150	Polymorphism, Restriction Fragment Length	Variation occurring within a species in the presence or length of DNA fragment generated by a specific endonuclease at a specific site in the genome. Such variations are generated by mutations that create or abolish recognition sites for these enzymes or change the length of the fragment.	RFLP,Restriction Fragment Length Polymorphism,RFLPs,Restriction Fragment Length Polymorphisms
D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children

D015235	HLA-B Antigens	Class I human histocompatibility (HLA) surface antigens encoded by more than 30 detectable alleles on locus B of the HLA complex, the most polymorphic of all the HLA specificities. Several of these antigens (e.g., HLA-B27, -B7, -B8) are strongly associated with predisposition to rheumatoid and other autoimmune disorders. Like other class I HLA determinants, they are involved in the cellular immune reactivity of cytolytic T lymphocytes.
