Description

Reported in an individual with global developmental delay, intractable epilepsy, severe hypotonia, and muscular atrophy, however, it is unclear whether a second PIGN variant was present (PMID: 33763700); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 29096607, 33763700)
