Chirag Patel gene: PIGB was added gene: PIGB was added to Intellectual disability, syndromic and non-syndromic_GHQ_VCGS. Sources: Literature Mode of inheritance for gene: PIGB was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: PIGB were set to PubMed: 31256876 Phenotypes for gene: PIGB were set to Epileptic encephalopathy, early infantile, 80; OMIM #618580 Review for gene: PIGB was set to GREEN Added comment: 10 unrelated families with biallelic mutations in PIGB, with global DD and/or ID, and seizures. Two had polymicrogyria, 4 had a peripheral neuropathy, and 2 had a clinical diagnosis of DOORS syndrome. Patient lymphocytes and fibroblasts showed variably decreased levels of cell surface GPI-anchored proteins, including CD16 and CD59. In vitro functional expression studies performed with some of the mutations in PIGB-null CHO cells showed that the mutant proteins were unable to fully restore expression of GPI-anchored surface proteins, consistent with a loss of function, although the mutations had variable effects.
