Generation of four induced pluripotent stem cell lines, GZWWTi001-A, GZWTZi001-A, GZWXYi001-A, and GZWXDi001-A, derived from peripheral blood mononuclear cells from a family with asparagine synthetase deficiency.

Asparagine synthetase (ASNS) deficiency (ASNSD; MIM #615574) is a rare neurodevelopmental disorder caused by mutations in the ASNS gene. The ASNS gene maps to cytogenetic band 7q21.3 and is 35 kb long. ASNSD is characterised by congenital microcephaly, severely delayed psychomotor development, seizures, and hyperekplexic activity. Here, we reported a family with compound heterozygous mutations in ASNS (NM_001178076:c.551C>T; c. 944A>C) and established induced pluripotent stem cells (iPSCs) from blood samples. To date, limited functional data have been reported to explain the underlying pathophysiology of ASNSD; therefore, iPSCs from these patients may be powerful tools for studying disease mechanisms.
