Dysmorphology Core (U24 Core)

描述（由申请人提供）：胎儿酒精谱系障碍（FASD）的诊断依赖于畸形模式的识别，包括生长和神经行为发育的改变，以及一系列特定的轻微颅面异常。由于产前酒精暴露的特定神经行为表型尚未确定，因此目前不可能在缺乏临床表型的情况下诊断FASD。Dysmorphology Core的责任是通过实施基于临床表型文件的标准方案，确保在所有研究中心对儿童FASD的准确和一致的诊断，该标准方案将在所有研究中心使用。由于该联盟将整合来自世界各地不同地点的研究人员，因此有必要在所有地点由具有丰富的产前酒精暴露儿童评估经验的一小部分核心人员负责FASD的诊断。

DESCRIPTION (provided by applicant): Diagnosis of the Fetal Alcohol Spectrum Disorder (FASD) is dependent on the identification of a pattern of malformation including alterations in growth and neurobehavioral development as well as a constellation of specific minor craniofacial anomalies. In that a neurobehavioral phenotype specific for prenatal alcohol exposure has not yet been identified, it is presently not possible to diagnose FASD in the absence of the clinical phenotype. It will be the responsibility of the Dysmorphology Core to assure accurate and consistent diagnosis of FASD in children at all consortium sites through implementation of a standard protocol based on documentation of the clinical phenotype which will be used at all sites. In that this consortium will integrate investigators from different sites throughout the world, it is imperative to have a small core of individuals with extensive experience in evaluation of children prenatally exposed to alcohol responsible for diagnosis of FASD at all sites. Identification of large numbers of children with FASD at various ages, each of whom has received a standardized clinical evaluation will provide the opportunity to gain new insight into a variety of issues relating to the clinical phenotype including the full range of structural defects in the disorder, physical features that are predictive of alterations in neurobehavioral development, the extent to which degrees of growth deficiency should be used to enhance specificity of diagnosis without loss of sensitivity, and will provide the opportunity to develop strategies to diagnose this disorder in the newborn period.
