Thirteen New Patients of PPP2R5D Gene Mutation and the Fine Profile of Genotype-Phenotype Correlation Unraveling the Pathogenic Mechanism Underlying Macrocephaly Phenotype.

variant spectrum. We confirmed the pathogenicity of novel variants through in vitro experiments. Our findings in genotype-phenotype relationship provide inspiration for genetic counseling and interpretation of variants. We also provide directions for further research on the mechanism of macrocephaly phenotype.
