Background: Methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism was reported as a genetic variant in liver steatosis and fibrosis. This is a study of the association between MTHFR C677T polymorphism and HCV core with severity of steatosis in HCV GT4 patients.
Methods: 111 HCV patients and 112 control subjects were recruited. Polymorphism was detected by RFLP analysis, core Ag was detected by ELISA.
Results: Combined HCV infection and MTHFR C677T polymorphism increases the risk to develop steatosis by 3.63- and 5.21-fold in subjects with single (CT) and double (TT) substitutions, respectively. Patients with chronic HCV infection had a 2.88- and 8.57-fold higher risk to develop steatosis in CT and TT genotypes, respectively, than patients with the (CC) genotype. No significant difference in core Ag titers were observed.
Conclusions: MTHFR C677T polymorphism is a valuable genetic marker for steatosis, while HCV core Ag titer had no association with grades of steatosis in GT4 infections.

Meta-analysis and systematic review for the genetic basis of cleft lip and palate.

Cleft lip and palate (CLP) are a usually inherited anomaly described as a gap in the oral cavity's upper lip and/or roof. The etiology of CLP involves both genetic and environmental factors. The current study aimed to examine the genetic basis of nonsyndromic (NS) CLP (NSCL/P) and its association with specific genetic polymorphisms.

Fragile X syndrome (FXS) presents with autism spectrum disorder (ASD), intellectual disability, developmental delay, seizures, hypotonia during infancy, joint laxity, behavioral issues, and characteristic facial features. The predominant mechanism is due to CGG trinucleotide repeat expansion of more than 200 repeats in the 5'UTR (untranslated region) of (Fragile X Messenger Ribonucleoprotein 1) causing promoter methylation and transcriptional silencing. However, not all patients presenting with the characteristic phenotype and point/frameshift mutations with deletions in have been described in the literature.

Background: Over the past decade, numerous studies have been conducted to determine the role of homocysteine and methylenetetrahydrofolate reductase () gene polymorphisms in the pathogenesis of polycystic ovary syndrome (PCOS), yet the results are inconsistent. The aim of the current study was to determine the association between homocysteine levels (Hcy), ) and A1298C polymorphisms, and pregnancy outcomes in Georgian women with PCOS.
Materials And Methods: This case-control study included 177 female participants, of which 96 women were diagnosed with PCOS, and 81 age-matched women were without PCOS.

Background: Unexplained recurrent miscarriage (RM) is still an unsolved reproductive health problem. Inherited thrombophilias have been one of the causes. Mutation in genes encoding coagulation proteins, including prothrombin (PT G20210A) and methylenetetrahydrofolate reductase (MTHFR) genes, increase tendency for venous thromboembolism.

The relationship between folate concentrations and stroke risk remains unestablished, and the mediation effect of homocysteine (Hcy) and interaction effect of methylenetetrahydrofolate reductase () gene polymorphism has yet to be investigated. This cohort study involved 4903 subjects derived from a Chinese community population. The association between folate and first stroke was examined in Cox proportional hazard regression models.
