| Remarks |
Well until age 14, then progress decline in IQ; progressive seizures, myoclonus; wheelchair bound at age 18; hospitalized; rarely speaks; cranial nerves intact; no retinal abnormalities; negative family history; normal EMI scan; normal bone marrow; donor subject is homozygous for a C>A transversion at nucleotide 386 of the NHLRC1 (EPM2B) gene (386C>A) resulting in the substitution of histidine for proline at codon 129 [Pro129His (P129H)] |
