This is the oldest English language journal in genetics. Founded by W. Bateson and R. C. Punnett in 1910, the Journal of Genetics was later edited by J. B. S. Haldane; later, Haldane and his wife, Helen Spurway brought the journal with them to India. After his death in 1964, Mrs. Haldane continued publication of the journal, with Madhav Gadgil and H. Sharat Chandra (Indian Institute of Science, Bangalore) and Suresh Jayakar (Laboratorio de Genetica Biochimica ed Evoluzionistica, Pavia) as editors, until her own death in 1977. In 1985, with the permission of Haldane’s heirs, the Indian Academy of Sciences resumed publication of the journal. The journal retains its traditional interest in evolutionary research that is of relevance to geneticists, even if not explicitly genetic in nature.

BACKGROUND Coronary artery disease (CAD) is a complex disease resulting from a combination of environmental and genetic factors. We hypothesized that polymorphisms hsa-mir-499 rs3746444 T/C, IRAK1 rs3027898 C/A and RANKL rs7984870 C/G might contribute to CAD susceptibility. METHODS We studied the association between the three polymorphisms and the risk of CAD in a Chinese population using 435 CAD patients and 480 controls. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used to perform the genotyping, and the differences were analysed. RESULTS When the hsa-mir-499 rs3746444 TT homozygote genotype was used as the reference group, the TC, CC or TC/CC genotypes were associated with a significantly increased risk of CAD [TC vs. TT: adjusted odds ratio (OR) 1.41, 95% confidence interval (CI) 1.02-1.94, p = 0.04; CC vs. TT: adjusted OR 3.14, 95% CI 1.77-5.56, p < 0.001; CC/TC vs. TT: adjusted OR 1.68, 95% CI 1.25-2.26, p < 0.001). In the recessive model, when the hsa-mir-499 rs3746444 TT/TC genotypes were used as the reference group, the CC homozygote genotype was associated with a significantly increased risk of CAD (adjusted OR 2.87, 95% CI 1.63-5.04, p < 0.001). Risk factors such as diabetes mellitus (DM), hypertension, smoking and low high-density ipoprotein cholesterol (HDL-c) were also associated with a significantly increased risk for CAD. Logistic regression analyses revealed that IRAK1 rs3027898 C/A and RANKL rs7984870 C/G polymorphisms were not associated with risk of CAD. CONCLUSIONS These findings suggested that the functional polymorphism hsa-mir-499 rs3746444 T/C is associated with CAD susceptibility.

Hsa-mir-499 rs3746444 T/C Polymorphism is Associated with Increased Risk of Coronary Artery Disease in a Chinese Population.

Introduction: Osteoprotegerin (OPG), a soluble decoy receptor secreted by osteoblasts, binds RANK-L, preventing stimulation of osteoclastogenesis. In the present study we aimed to investigate the impact of OPG variants and susceptibility to childhood acute lymphocytic leukemia (ALL) in a sample of Iranian population. Methods: This case-control study was done on 98 ALL and 124 healthy children. We genotyped the polymorphisms using tetra-primer ARMS-PCR (T-ARMS-PCR). Results: Our findings showed that neither rs3102735 nor rs2073617 variants were associated with ALL in a sample of Iranian population. Concerning rs3102735 polymorphism, the age of ALL predispositions was significantly higher in TC+CC genotype than TT genotype (P=0.032). Furthermore, the CSF involvement was significantly higher in ALL subjects carrying TC+CC genotype (p=0.044). Conclusion: We found no association between OPG (rs3102735, rs2073617) gene polymorphisms and risk of childhood ALL. Further studies with larger sample sizes and various ethnicities are necessary to verify our findings.

B ligand (RANKL), its receptor RANK and osteo-protegerin (OPG) are members of tumour necrosis fac-tor (TNF) superfamily and they form a key cytokine triadinvolved in bone metabolism, speciﬁcally osteoclastogen-esis (Khosla 2001; Boyce and Xing 2008). Recent stud-ies have demonstrated that OPG/RANK/RANKL system isinvolved in plaque instability and rupture by inducing plaquecalciﬁcation (Panizo
