Background: Osteogenesis imperfecta (OI), a rare autosomal inheritable disorder characterized by bone fragility and skeletal deformity, is caused by pathogenic variants in genes impairing the synthesis and processing of extracellular matrix protein collagen type I. With the use of next-generation sequencing and panels approaches, an increasing number of OI patients can be confirmed and new pathogenic variants can be discovered. This study sought to identify pathogenic gene variants in a Chinese family with OI I.

Methods: Patients who underwent anterior mediastinal lesion and LIV resection from January 2010 to December 2018 in the Department of Thoracic Surgery of Tangdu Hospital, Air Force Medical University, were followed up, and preoperative, intraoperative and postoperative factors were analyzed.
Results: Forty-eight patients who underwent anterior mediastinal lesion and LIV resection from January 2010 to December 2018, except for 2 who died of lung infection-induced respiratory failure, were followed up, with an average follow-up time of 32 months (range, 6-72 months).
Background: Mucopolysaccharidosis type I (MPS I) is a rare autosomal storage disorder resulting from the defective alpha-L-iduronidase (encoded by IDUA) enzyme activity and accumulation of glycosaminoglycans (GAGs) in lysosomes. So far, more than 100 IDUA causative mutations have been identified leading to three MPS I phenotypic subtypes: Hurler syndrome (severe form), Hurler/Scheie syndrome (intermediate form), and Scheie syndrome (mild form).
Methods: Whole-exome sequencing (WES) was performed to identify the underlying genetic mutations.

Background: Fabry disease (FD), a rare X-linked α-galactosidase A (GLA) deficiency, resulting in progressive lysosomal accumulation of globotriaosylceramide in a variety of cell types. More and more disease-causing mutations in GLA have been identified in FD due to the advancement of molecular diagnostic tools. We found a novel mutation in a Chinese family with predominant Fabry's disease nephropathy.

Objective: To study the instability of mitochondrial DNA(mt DNA) D-loop region genes in patients with Leukemia.
Methods: The HV-1 and HV-2 regions of D-loop region in 24 patients with leukemia were amplificated and sequenced, then their results were compared with revised Cambridge reference sequence (rCRS) and Databank mtDB. The mutation rate was detected by SPSS 22.
Fabry disease (FD) is a rare X-linked α-galactosidase A () deficiency, resulting in progressive lysosomal accumulation of globotriaosylceramide (Gb3) in a variety of cell types. Here, we report a novel splicing mutation (c.801 + 1G > A) that results in alternative splicing in of a FD patient with variable phenotypic presentations of renal involvement.

Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA (lncRNA), and can induce cancer cell proliferation, while lncRNAs, generally are able to act as microRNA (miRNA) sponges. The latter is a type of competitive endogenous RNA (ceRNA) that regulates expression of the targeting miRNAs and protein-coding genes.

ATP-binding cassette (ABC) transporters are associated with poor response to chemotherapy, and confer a poor prognosis in various malignancies. However, the association between the expression of the ABC sub-family G member 4 (ABCG4) and prognosis in patients with non-small-cell lung cancer (NSCLC) remains unclear. NSCLC tissue samples (n = 140) and normal lung tissue samples (n = 90) were resected from patients with stage II to IV NSCLC between May 2004 and May 2009.
