Comment
(from OMIM) In 2 sibs, born of consanguineous Syrian parents, with MRT42, Murakami et al. (2014) identified a homozygous mutation in the PGAP1 gene. Both had neonatal hypotonia and severely delayed psychomotor development (IQ below 35) with some stereotypic movements. One had both major and absence epilepsy. Brain CT scan of 1 patient showed pronounced brain atrophy. Lymphoblastoid cells derived from the patients showed normal expression of glycosylphosphatidylinositol (GPI)-anchored proteins, but these proteins were resistant to cleavage by PI-specific phospholipase C. These results indicated abnormal GPI structure due to a loss of PGAP1 enzyme activity early in the remodeling process of GPI-anchored proteins.
