| Allelic Variant 1 |
R1743Q; TUBEROUS SCLEROSIS, TYPE 2 |
| Identified Mutation |
ARG1743GLN |
| Remark |
Clinically affected; diagnosed at age 2; mental retardation with IQ of 66; adenoma sebaceum over the nose and cheeks in a butterfly distribution; seizures that began about 6 months of age; numerous, variable sized areas of depigmentation over the legs, arms and back; shagreen patch in midline of upper back; forehead plaque; abnormal EEG at age 7, which showed right frontotemporal and left occipital focal abnormalities; donor subject is heterozygous for a G>A transition at nucleotide 5228 in exon 40 of the TSC2 gene resulting in a substitution of glutamine for arginine at codon 1743 [Arg1743Gln (R1743Q)]; same donor as GM06101 lymphocyte; see GM25318 for iPSC derived from this fibroblast. |
