Craniosynostosis is a rare disease in which one or more of the cranial sutures in an infant skull prematurely fuses by turning into bone,with a prevalence of 1 in 2,000—2,500 individuals from reports in Western countries(wilkie et al.,2017).It may restrict the growth of the brain,leading to some degree of morphological and functional abnormalities,and may affect the neurocognitive function of infants(lattanzi et al.,2017).Genetic variants underlying craniosynostosis have been identified in cohort studies in Western populations.

以天然海泡石(sepiolite,sEP)和用十六烷基三甲基溴化铵(CTAB)改性的有机海泡石(Organic-sepio-lite,OsEP)为填料,采用熔融共混法分别制备聚丙烯/海泡石(PP/sEP)、聚丙烯/有机海泡石(PP/OsEP)复合材料。根据锥形量热仪实验数据,选择热释放速率(HRR)、火灾性能指数(FPI)、生烟速率(sPR)、质量损失率(mlR)和燃烧残留物形貌分析,考察海泡石和有机海泡石对聚丙烯(PP)燃烧性能的影响。结果表明:CTAB以季铵盐的形式通过吸附方式键接在海泡石表面,改性后缔合和游离两种形式的-OH基团增加;阻燃PP的FPI有所提高,HRR最大降幅为66%,sPR由纯PP的0.117m2/s下降为0.0704m2/s,mlR由0.45g/s下降到0.20g/s;当有机海泡石阻燃剂添加量达到10%时,复合材料在燃烧过程中形成炭层。

Purpose: To determine the underlying molecular genetic basis of a retinal dystrophy identified in a 4- generation family and to examine the phenotype and the degree of intrafamilial variability. Design: Prospective case series. Participants: six affected individuals from a nonconsanguineous British family. methods: Detailed ophthalmologic examination, color fundus photography, autofluorescence imaging, and electrophysiologic assessment were performed. Blood samples were taken for DNA extraction, and mutation screening of GUCA1A, the gene encoding guanylate cyclase-activating protein 1 (GCAP1), was undertaken. Results: All affected subjects complained of mild photophobia and reduced central and color vision. Onset was between the third and fifth decade, with subsequent gradual deterioration of visual acuity and color vision. Visual acuity ranged between 6/9 and counting fingers. Color vision was either absent or markedly reduced along all 3 color axes. A range of macular appearances was seen, varying from mild retinal pigment epithelial disturbance to extensive atrophy. Electrophysiologic testing revealed a range of electrophysiologic abnormalities: isolated cone electroretinography abnormalities, reduced cone and rod responses (with cone loss greater than rod), and isolated macular dysfunction. The 4 coding exons of GUCA1A were screened for mutations in affected and unaffected family members. A single transition, A319G, causing a nonconservative missense substitution, Tyr99Cys, segregated uniquely in all affected subjects. Conclusions: The Tyr99Cys GUCA1A mutation has been previously shown to cause autosomal dominant progressive cone dystrophy. This is the first report of this mutation also causing both cone-rod dystrophy and isolated macular dysfunction. The phenotypic variation described here exemplifies the intrafamilial heterogeneity of retinal dysfunction that can be observed in persons harboring the same mutation and chromosomal segment.

The GP130 cytokine receptor subunit encoded by Il6sT is the shared receptor for ten cytokines of the Il-6 family. We describe a homozygous non-synonymous variant in Il6 sT(p.R281 Q) in a patient with craniosynostosis and retained deciduous teeth. We characterize the impact of the variant on cytokine signaling in vitro using transfected cell lines as well as primary patient-derived cells and support these findings using a mouse model with the corresponding genome-edited variant Il6 st p.R279 Q. We show that human GP130 p.R281 Q is associated with selective loss of Il-11 signaling without affecting Il-6, Il-27, Osm, lIF, CT1, ClC, and CNTF signaling. In mice Il6 st p.R279 Q lowers litter size and causes facial synostosis and teeth abnormalities. The effect on Il-11 signaling caused by the GP130 variant shows incomplete penetrance but phenocopies aspects of Il11 RA deficiency in humans and mice. Our data show that a genetic variant in a pleiotropic cytokine receptor can have remarkably selective defects.
