Sialuria-Related Intellectual Disability in Children and Adolescent of Pakistan: Tenth Patient Described has a Novel Mutation in GNE gene.

Sialuria-Related Intellectual Disability in Children and Adolescent of Pakistan: Tenth Patient Described has a Novel Mutation in GNE gene. CNS Neurol Disord Drug Targets. 2020 Feb 12;: Authors: Ishtiaq H, Siddiqui S, Nawaz R, Jamali KS, Khan AG Abstract Sialuria is a rare inborn error of metabolism caused by excessive synthesis of sialic acid due to the mutation in the binding site of the cytidine monophosphate-sialic acid of UDP-GlcNAc 2-epimerase/ManNAc kinase (GNE/MNK). This is the first study investigating the molecular basis of neuronal disorders exhibiting sialuria in Pakistani children/ adolescents. Current study genotyped GNE SNPs rs121908621, rs121908622 and rs121908623 by using PCR, RFLP, and DNA sequencing methods. Socioeconomic and clinical histories were also recorded. Our data suggest that clinical symptoms and financial status play a significant role in conferring sialuria related Intellectual Disability (ID). SNP: rs121908623 showed G/A substitution (R263Q) in the GNE gene. We have identified one case study in Pakistan so this makes our research a leap forward towards the identification of the 10th case study worldwide. PMID: 32053088 [PubMed - as supplied by publisher]
