Association of two single nucleotide polymorphisms rs10407022 and rs3741664 with the risk of primary ovarian insufficiency in a sample of Iraqi women.

Primary ovarian insufficiency (POI) can be a devastating disease impacting women below the age of forty. This involves a major decrease in the amount and quality of oocytes, or ovarian reserve in a woman. The distribution of single-nucleotide polymorphisms, rs10407022 and rs3741664, in Iraqi people and its association with primary ovarian insufficiency is the main objective of this study. The mean of FSH and LH levels of patients with POI was higher than control, while the mean of AMH levels of patients was lower compared to control. For rs10407022, the GT and TT genotypes were positively associated with the risk of POI. For the rs3741664, the AG genotype was negatively associated with the risk of POI. The results lead to the main conclusion that rs10407022 and rs3741664 polymorphisms may significantly affected the serum levels of AMH and FSH and thus affect POI etiology.

Pharmacokinetic Effect of MDR Gene Polymorphism rs2032582 on the Therapeutic Response in Iraqi Patients with Acute Myeloid Leukemia.

BACKGROUND: The main problem in treatment of leukemia patients is the chemotherapy resistance which is a main concern in recent years. The cause of chemotherapy drug resistance is related to MDR gene which is located on chromosome 7 (7q21-31) and it is mainly connected with energy-dependent efflux (P-glycoprotein). This study was conducted to assess the correlation between MDR polymorphism and chemotherapy efficiency with Vincristine in a sample of Iraqi Acute Myeloid Leukemia (AML) patients. METHODS: The blood sample of 200 AML patients and 200 controls were collected and the frequency of rs2032582 was calculated through sequencing and then the role of different genetic patterns was evaluated on cancer cells by MTT assay. RESULTS: The results indicate that GG and TT genotypes (20 and 20.5% from total patients count) are more frequent in Iraqi AML patients than other genetic patterns in MDR gene and also the genotype TA is more sensitive to Vincristine chemotherapy than other genotypes. CONCLUSION: It seems that genetic pattern is the main factor in determination of chemotherapy of AML patients, and patients should not undergo chemotherapy with such drugs, especially Vincristine.
