Crouzon Syndrome is an autosomal dominant syndromic craniosynostosis characterized by premature closure of cranial sutures, exophthalmos, and midface hypoplasia. It is caused by multiple mutations in the fibroblast growth factor receptor 2 (FGFR2). We describe prenatal genetic testing of FGFR2 in a fetus of a mother whose previous child had Crouzon Syndrome due to an apparently de novo mutation...
یافته های جدید نشان داده اند، تغییرات اپی ژنتیکی عوامل کلیدی موثر در کارسینوژنز پستان هستند. ناهنجاری الگوی متیلاسیون از جمله پیامدهای تغییرات اپی ژنتیکی می باشد. متیلاسیون dna در تنظیم فعالیت ژن نقش دارد. متیلاسیون غیرنرمال dna با انواع بیماریها مانند سرطان در ارتباط است. به دلیل اهمیت نقش اپی ژنتیک در ایجاد سرطان بویژه سرطان سینه، به نظر می آید، ایجاد روش های موثر در پیش بینی، تشخیص و پیگیری ...
Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, and generally considered to be caused by environment and genetic factors. In this study, we combined a genome-wide haplotype association study (GWHAS) and gene prioritization strategy to mine AML-related genetic affect factors and understand its pathogenesis. A total of 175 AML patients were downloaded from the public ...
Beare-Stevenson cutis gyrata syndrome: A new case of a c.1124C↷G (Y375C) mutation in the FGFR2 gene.
Beare-Stevenson syndrome (BSS) (MIM#123790) is a rare disorder characterized by craniofacial anomalies and cutis gyrata associated with anogenital anomalies and prominent umbilical stump. There are few reports on the syndrome, and molecular analysis has revealed the involvement of two closely spaced mutations within the FGFR2 gene: c.1115C↷G (p.S372C) and c.1124C↷G (p.Y375C). We herein describe...
Apert syndrome is a congenital disorder characterized by severe skull malformations and caused by one of two missense mutations, S252W and P253R, on fibroblast growth factor receptor 2 (FGFR2). The molecular bases underlying differential Apert syndrome phenotypes are still poorly understood and it is unclear why cleft palate is more frequent in patients carrying the S252W mutation. Taking advan...
Lacrimo-auriculo-dento-digital (LADD) syndrome is characterized by abnormalities in lacrimal and salivary glands, in teeth, and in the distal limbs. Genetic studies have implicated heterozygous mutations in fibroblast growth factor 10 (FGF10) and in FGF receptor 2 (FGFR2) in LADD syndrome. However, it is not clear whether LADD syndrome mutations (LADD mutations) are gain- or loss-of-function mu...
Development of external genitalia in mammalian embryos requires tight coordination of a complex series of morphogenetic events involving outgrowth, proximodistal and dorsoventral patterning, and epithelial tubulogenesis. Hypospadias is a congenital defect of the external genitalia that results from failure of urethral tube closure. Although this is the second most common birth defect in humans,...
The fibroblast growth factor and receptor system (FGF/FGFR) mediates cell communication and pattern formation in many tissue types (e.g., osseous, nervous, vascular). In those craniosynostosis syndromes caused by FGFR1-3 mutations, alteration of signaling in the FGF/FGFR system leads to dysmorphology of the skull, brain and limbs, among other organs. Since this molecular pathway is widely expre...
Genetic alterations in the fibroblast growth factor receptor (FGFR) pathway are promising therapeutic targets in many cancers, including intrahepatic cholangiocarcinoma (ICC). The FGFR inhibitor BGJ398 displayed encouraging efficacy in patients with FGFR2 fusion-positive ICC in a phase II trial, but the durability of response was limited in some patients. Here, we report the molecular basis for...
