Abstract：
:Patients with germline phosphatidylinositol glycan biosynthesis class A (PIGA) related disorder have historically been categorized into one of two distinct subtypes: a severe form which is often fatal, and a less severe form. However, the increasing number of cases with features indicative of both subtypes raise the possibility of a phenotypic spectrum associated with PIGA disorder. In order to further characterize this phenotypic spectrum, we present two patients with features of both the severe and less severe subtypes with a review of phenotypes reported to date in the literature. In eight year old patient 1, a maternally inherited PIGA likely pathogenic variant was discovered using exome sequencing. He presented with myoclonic epilepsy, mild intellectual disability, spastic diplegia, developmental motor delay, and autism spectrum disorder. Patient 2 is a 13 year old with focal epilepsy, profound developmental delay, coarse facial features, severe intellectual disability and autism spectrum disorder. A de novo PIGA likely pathogenic variant was found through exome sequencing. Both patients had normal alkaline phosphatase levels and are without related organ abnormalities. We conclude that pathogenic PIGA variants cause a spectrum of phenotypes rather than the categories of "severe" and "less severe" as previously posited.
