Novel compound heterozygous mutations in GPT2 linked to microcephaly, and intellectual developmental disability with or without spastic paraplegia.

Abstract excerpt

We here describe novel compound heterozygous missense variants, NM_133443:c.[400C>T] and NM_133443:[1435G>A], in the glutamic-pyruvic transaminase 2 (GPT2) gene in a large consanguineous family with two affected siblings diagnosed with microcephaly intellectual disability and developmental delay (IDD). In addition to these clinical phenotypes, the male sibling has spastic paraplegia, and the female sibling has...
