Zornitza Stark gene: PIGU was added gene: PIGU was added to Congenital Disorders of Glycosylation. Sources: Expert list Mode of inheritance for gene: PIGU was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: PIGU were set to 31353022 Phenotypes for gene: PIGU were set to Glycosylphosphatidylinositol biosynthesis defect 21, OMIM #618590 Review for gene: PIGU was set to GREEN Added comment: 5 patients from 3 unrelated families, with homozygous missense mutations in the PIGU gene. All individuals presented with global DD, severe-to-profound ID, muscular hypotonia, seizures, brain anomalies, scoliosis, and mild facial dysmorphism. Flow cytometric analysis of patient granulocytes showed a characteristic pattern, with reduced cell surface expression of CD16 and CD24. In addition, patient B cells showed increased expression of free GPI anchors determined by a specific antibody, T5. The findings suggested that PIGU mutations reduce the function of the GPI transamidase complex, leading to accumulation of free GPI anchors on the cell surface. Sources: Expert list |
