| Allelic Variant 1 |
164874.0007; RETT SYNDROME, CONGENITAL VARIANT |
| Identified Mutation |
c.460dupG (p.Glu154Glyfs*301); In 2 unrelated patients with the congenital variant of Rett syndrome (613454), Kortum et al. (2011) identified a heterozygous de novo 1-bp duplication (460dupG), resulting in a duplication of guanine after 7 subsequent guanine nucleotides in the FOXG1 gene. The recurrence of this mutation suggested that this guanine stretch is prone to replication errors, thus representing a mutation hotspot. |
| Remarks |
Clinically affected; normal pregnancy and birth; delay apparent by 12 weeks (not smiling until 20 weeks, poor head control, but was thriving); infrequent focal (left-sided) seizures; examined at 2y 11m: able to pick up food; MRI showed complete agenesis of corpus callosum; dystonia (treated with L-DOPA); mutation in FOXG1 gene: c.460dupG (p.E154GfsX301); same subject as GM27620 (iPSC) |
