| Remarks |
The donor has clinical features of spastic appearance, sunken eyes with prominent mandible and upper teeth, tight heel cords, optic atrophy, bilateral hearing loss, and minimal growth since age 4. CT scan showed bilateral basal ganglia calcifications and cerebellar calcifications with moderate atrophy of the cortices. Studies of this cell culture done by Dr. James E Cleaver showed it to be clearly UV sensitive with DNA excision repair close to normal (82%). This is consistent with a diagnosis of Cockayne syndrome. The skin biopsy was taken ante-mortem on 1/28/88 from the right forearm. The culture was initiated from explants of minced skin tissue. The morphology is fibroblast-like. Culture was frozen at passage 4 and PDL is not known. |
