411delG |
| Remarks |
Clinically affected with incomplete features of Rett syndrome; at birth her right leg had faint red papules that extended from groin to calf; papules were replaced by hyperpigmentation at age 1 month; lesion biopsy at age 3 years revealed prominent spongiosis and cytoid bodies in the dermis together with superficial perivascular infiltrate, prominent pigment incontinence and abundant eosinophils; histopathology was consistent with diagnosis of incontinentia pigmenti; regression of speech occurred at age 2 months; she gradually lost learned hand skills and developed frequent hand-washing movements; autistic features with gaze avoidance and bruxism; hypotonia; donor subject has a 1 bp deletion at nucleotide 411 in exon 3 of the MECP2 gene (411delG) resulting in a premature stop codon [Leu168Ter (L138X)] |
