| 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; diagnosed as 47,XXX at CVS for maternal age (40 years); microcephaly suspected at 19/40 US scan; microcephanic although occipitofrontal head circumference (OFC) did grow along centile lines; poor feeding and ‘colic’; admitted for investigation at 3 months; seizures from infancy, severe from 2 years; showed some Rett-like behaviors; seizures remained a problem but improved from 9-10 years; on treatment for seizures, dystonia, poor sleeping and reflux when assessed at 18 years; mutation in FOXG1 gene: c.460dupG (p.E154GfsX301). |
