Matrix metalloproteinases (MMPs) play important roles in tumorigenesis. The variant in MMP-9 −1562 C/T (single nucleotide polymorphisms labeled rs3918242) has been extensively evaluated as predisposing factors to digestive cancers susceptibility. However, most of these studies only contained a small number of subjects and they showed conflicting results. Therefore, to elucidate these associations,...
Acephalic spermatozoa is an extremely rare disease associated with primary infertility. A recent study showed that genetic alterations in the SUN5 gene lead to this disease, and SUN5 mutations could explain the disease in about half of the patients. Therefore, in the present study, to re-visit the genetic contribution of SUN5 mutations to acephalic spermatozoa, we recruited 15 unrelated affected individuals...
Severe oligozoospermia (SO) is a common disease resulting in male infertility; however, its pathophysiology remains unclear. Here, we report two brothers with SO. Whole-exome sequencing (WES) identified a hemizygous variant in HAUS7 (c.G386T:p.G129V), an X-linked gene. HAUS7 has been reported to play a role in the meiotic maturation and chromosome alignment of germ cells. The two patients inherited...
Polycystic kidney disease (PKD) is a common inherited disease that is characterized by a progressive development of renal cysts. Approximately 85% of PKD cases are due to mutations in the polycystin 1 (PKD1) gene. Here, we report a pedigree containing nine patients with autosomal dominant PKD (ADPKD). Using targeted exome sequencing of PKD1 and PKD2 genes, we identified a novel heterozygous frameshift...
Multiple morphological abnormalities of the sperm flagella (MMAF) is a rare disease associated with primary infertility; however, ~50% of the genetic alterations associated with MMAF remain unclear. Here, we reported the case of a 30-year-old infertile male from a consanguineous family. Whole-exome sequencing identified a homozygous mutation in the CEP135 gene (c.A1364T:p.D455V), with CEP135 previously...
Breast cancer is the most common cause of cancer death in women and ranks second among cancer deaths. Metastasis is the main cause of death in breast cancer patients. However, the mechanisms underlying the invasion and metastasis of breast cancer cells remain largely elusive. Here we report that the protein PRAME, a tumor-associated antigen isolated from a melanoma, plays a role in preventing the...
It is widely accepted that the incidence of chromosomal aberration is 10–15.2% in the azoospermic male; however, the exact genetic damages are currently unknown for more than 40% of azoospermia. To elucidate the causative gene defects, we used the next generation sequencing (NGS) to map the breakpoints of a chromosome insertion from an azoospermic male who carries a balanced, maternally inherited...
Δ6-Desaturase is the rate-limiting enzyme involved in highly unsaturated fatty acid (HUFA) biosynthesis. There is very little information on the evolution and functional characterization of Δ6Fad-a and Δ6Fad-b in common carp (Cyprinus carpio var. Jian). In the present study, the genomic sequences and structures of two putative Δ6-desaturase-like genes in common carp genome were obtained. We investigated...
The genus Mentha comprises a group of aromatic plants with worldwide distribution. Because of frequent interspecific hybridization, the genetic relationships within the genus are not clearly understood. Limonene synthase, which catalyses the first committed step in the essential oil monoterpene biosynthetic pathway, is considered to be a possible rate limiting enzyme. With the homology-based cloning...
The T241M polymorphism in the X-ray cross-complementing group 3 (XRCC3) had been implicated in cancer susceptibility. The previous published data on the association between XRCC3 T241M polymorphism and cancer risk remained controversial. Hence, we performed a meta-analysis to investigate the association between cancer susceptibility and XRCC3 T241M (61,861 cases and 84,584 controls from 157 studies)...
Our previous studies identified a functional SNP, R952Q in the LRP8 gene, that was associated with increased platelet activation and familial and early-onset coronary artery disease (CAD) and myocardial infarction (MI) in American and Italian Caucasian populations. In this study, we analyzed four additional SNPs near R952Q (rs7546246, rs2297660, rs3737983, rs5177) to identify a specific LRP8 SNP haplotype...
Human synpolydactyly (SPD), belonging to syndactyly (SD) II, is an inherited autosomal-dominant limb malformation characterized by SD of finger 3 or 4 or toe 4 or 5, usually with digit duplication. Previous studies have demonstrated that homeobox protein D13 (HOXD13) is responsible for this Mendelian disorder. In this paper, we report on a family with SPD — 7 members show typical SPD malformations...
