手指伸屈联动与灵活表型的调查与遗传分析

Investigation and genetic analysis of finger extension linkage andflexibilityAbstract Many morphological and behavioral characteristics of human beings areimportant contents of genetic research,The brain's control of fine finger movements isundoubtedly the result of nerve control over muscle groups,We found that some humanindividuals are not affected by each other's fingers bending,And some individuals showdifferent degrees of finger bending linkage phenomenon The finger bending linkagephenotype has not been listed in the human phenotype genetic database,Neurobiology,anatomy and family genetics have not been reported,The purpose of this study is toinvestigate the phenotype of finger bending linkage and its inheritance pattern,It ispreliminarily determined to be autosomal dominant inheritance,which denies the way ofcompanion inheritance The classification and classification of finger bending linkagephenotype were made.To provide data support for the subsequent research on thedevelopment and genetic law of the flexor muscle group of fingers and the neurons it controls,It's a pioneering research,It is expected to provide genetic theoretical basis for the applicationof brain signal control prosthesis,manipulator operation,hand disability rehabilitation andtreatment.Keywords Human genetics;Genetic law;Familial inheritance;Finger bendingphenotype
