Aminoglycoside induced ototoxicity associated with mitochondrial DNA mutations
Publication date: Available online 16 June 2016 Source:Egyptian Journal of Medical Human Genetics Author(s): Joseph Foster, Mustafa Tekin Despite the risk of permanent ototoxic effects, aminoglycosides remain commonly utilized antibiotics worldwide due to low cost and efficiency in treating severe infections. Over the last two decades, mitochondrial mutations have been shown to enhance the likelihood of ototoxic injury. In particular the 1555A>G mutation in the mitochondrial gene MTRNR1 has been strongly associated with the onset of aminoglycoside-induced deafness; though pinning down the exact mechanism of ...

Association between interleukin-4 (IL-4), gene polymorphisms (C-589T, T+2979G, and C-33T) and migraine susceptibility in Iranian population: A case–control study
Publication date: Available online 10 June 2016 Source:Egyptian Journal of Medical Human Genetics Author(s): Nourollah Ramroodi, Mohammad Reza Javan, Nima Sanadgol, Mehdi Jahantigh, Tooba Nakhzari Khodakheir, Nasrin Ranjbar Background Migraine is a chronic neurological disease characterized by recurrent moderate to severe headaches commonly in association with neuro-inflammation. Interleukin-4 (IL-4), an anti-inflammatory cytokine, plays an important role in modulating pain threshold and has an essential role in stimulation of pain receptors in the trigeminal nerve fibers. Aim of the study The current stu...

Circulating MiRNA-21 and programed cell death (PDCD) 4 gene expression in hepatocellular carcinoma (HCC) in Egyptian patients
Conclusion Circulating miRNA-21 could be a novel early diagnostic and prognostic biomarker for detection of HCC. Approaches interfering with the miRNA-21/PDCD4-axis, or releasing PDCD4 expression, may have a strong basis for therapeutic uses in cancer in the future.

Determination of DNA profiling of siwak and toothbrush samples used in Kingdom of Saudi Arabia
Conclusion Siwak contains enough quantity of DNA, and retained good DNA profiling; and when compared to toothbrushes, siwak is a reasonable source of DNA profiling when found at the scene of crime. In addition, time of storage up to 4months had no or little effects on results. (Source: Egyptian Journal of Medical Human Genetics)

A retrospective study on fourteen year hemoglobin genotype variants recorded at five government hospitals in Akure, Ondo State, Southwestern Nigeria
This study analyzed fourteen year (2000–2013) hemoglobin (Hb) genotypes records from five state government hospitals in Akure, Ondo State, Southwestern, Nigeria. In the fourteen year record, a total of 56,218 hemoglobin genotypes were subjected to analyses in terms of a variety of hemoglobin genotypes and their prevalence in the area. The gene frequency was also calculated for this trait among the residents in Akure metropolis. Results and conclusion Six hemoglobin genotypes were identified as HbAA, HbAS, HbAC, HbSS, HbSC and HbCC. The overall average values of their prevalence in decreasing order were HbAA (88.11%)&am...

Risk factors for congenital anomalies in high risk pregnant women: A large study from South India
Conclusion High prevalence of CAs was found in HRP women compared to general population. Low parental age contributed toward CAs in primi gravida women while consanguinity was found to be a predisposing factor for CAs in HRP with previous BOH. Toxoplasmosis conferred risk for CAs in HRP women with previous normal pregnancies. (Source: Egyptian Journal of Medical Human Genetics)

Magnesium, zinc and copper estimation in children with attention deficit hyperactivity disorder (ADHD)
Conclusion Children with ADHD have lower levels of zinc, copper and magnesium compared to both laboratory reference ranges and to normal controls in both hair and serum. These deficiencies are correlated with the core symptoms of ADHD. (Source: Egyptian Journal of Medical Human Genetics)

The association of single nucleotide polymorphism of interleukin-21 gene and serum interleukin-21 levels with systemic lupus erythematosus
Conclusion IL-21 plays an important role in the immune-pathogenesis of SLE and could be used as a possible target for novel immunotherapy. The T allele of SNP rs2221903 suggests that the IL-21 gene may contribute to an inherited predisposition to SLE. (Source: Egyptian Journal of Medical Human Genetics)

MTRR gene variants may predispose to the risk of Congenital Heart Disease in Down syndrome patients of Indian origin
Conclusion Results from this study indicate that the MTRR C524T and A66G polymorphisms influence the risk of the occurrence of CHD in DS patients of Indian Origin. This is the first report from India highlighting the potential association of MTRR C524T and A66G polymorphisms with CHD in DS. We are also the first one to report two novel polymorphisms, T19775C and 19778_19778delG in DS with CHD group. Hence these four polymorphisms can be used to evaluate the risk of CHD in DS patients.
