Intellectual disability (ID) and retinal dystrophy (RD) are the frequently found features of multiple syndromes involving additional systemic manifestations. Here, we studied a family with four members presenting severe ID and retinitis pigmentosa (RP). Using genome wide genotyping and exome sequencing, we identified a nonsense variant c.747 C > A (p.Tyr249Ter) in exon 7 of AGPAT3which co-segregates with the disease phenotype. Western blot analysis of overexpressed WT and mutant AGPAT3 in HEK293T cells showed the absence of AGPAT3, suggesting instability of the truncated protein. Knockdown of Agpat3in the embryonic mouse brain caused marked deficits in neuronal migration, strongly suggesting that reduced expression of AGPAT3 affects neuronal function. Altogether, our data indicates that AGPAT3activity is essential for neuronal functioning and loss of its activity probably causes intellectual disability and retinitis pigmentosa (IDRP) syndrome. |
