Mol Med Rep 2018; 18:2417-2426. [PMID: 29956771 DOI: 10.3892/mmr.2018.9202] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2017] [Accepted: 05/10/2018] [Indexed: 11/06/2022] Open
Abstract
Recurrent pregnancy loss (RPL) is defined as ≥2 consecutive pregnancy losses, and can be caused by various factors, including genetics, chromosomal abnormalities, thrombophilia, immune disorders, nutritional factors, environmental factors, psychological stress or maternal infections; however, as many as 50% of RPL cases are idiopathic. In the present study, the role of genetic polymorphisms in RPL was investigated. Four gene polymorphisms were selected by whole exome sequencing, including membrane spanning 4‑domains A14 (MS4A14)D>I (rs3217518), solute carrier family 2 member 7 (SLC2A7)D>I (rs60746313), pregnancy specific β‑1‑glycoprotein 9 (PSG9)C>T (rs3746297) and ATP binding cassette subfamily B member 5 (ABCB5)C>G (rs17143187), and the aim was to investigate their association with RPL in Korean women. Genotyping was performed using polymerase chain reaction‑restriction fragment length polymorphism assay. Allele combination analysis revealed that the four‑allele combination I‑D‑T‑G, (MS4A14/SLC2A7/PSG9/ABCB5) was associated with a decreased risk for RPL. Interaction analysis demonstrated that the following genotypes: MS4A14 DI+II, SLC2A DI+II and ABCB 5 CG+GG, were associated with a prothrombin time ≥12 sec and with RPL risk. It may be concluded that the four gene polymorphisms do not affect RPL individually, but are associated with RPL when in combination with other genes or blood coagulation factors. Notably, the MS4A14 I allele, with a prothrombin time ≥12 sec, may be a potential biomarker for diagnosis, prevention and prognosis of RPL.

Park YS, An HJ, Kim JO, Kim WS, Han IB, Kim OJ, Kim NK, Kim DS. The Role of RNF213 4810G>A and 4950G>A Variants in Patients with Moyamoya Disease in Korea. Int J Mol Sci 2017; 18:ijms18112477. [PMID: 29160859 PMCID: PMC5713443 DOI: 10.3390/ijms18112477] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2017] [Revised: 11/16/2017] [Accepted: 11/18/2017] [Indexed: 11/16/2022] Open
Abstract
Although a founder variant of RNF213 4810G>A is a major genetic risk factor for moyamoya disease (MMD) in East Asians, the frequency and disease susceptibility of RNF213 variants remain largely unknown. This study investigated the mutation analysis of RNF213 (4448, 4810, 4863, and 4950) between Korean MMD and healthy controls. We performed a polymerase chain reaction-restriction fragment length polymorphism analysis. To identify the association between RNF213 gene polymorphisms and MMD disease, we performed statistical analyses such as multivariable logistic regression and Fisher’s exact test. Genetic data from 117 MMD patients were analyzed and compared with 253 healthy controls. We assessed and compared single nucleotide polymorphisms of RNF213 (4448, 4810, 4863, and 4950) between MMD and control groups. We performed genome-wide association studies to investigate the genetic pathophysiology of MMD. Among the RNF213 variants (4448G>A, 4810G>A, 4863G>A, and 4950G>A), RNF213 4810G>A and 4950G>A variants were more frequent in MMD patients. In a subgroup analysis, the RNF213 4810G>A was more frequent in moyamoya disease, and the comparison with GG+AA genotype was also significantly different in moyamoya patients. These results confirm that RNF213 4810G>A and RNF213 4950G>A were more frequent in MMD patients. We have confirmed that RNF213 4810G>A and 4950G>A are strongly associated with Korean MMD in children and adults as well as for the ischemic and hemorrhagic types.
