| Remarks |
Clinically affected; skin biopsy taken from inner forearm; complementation group 8; hypotonic with no deep tendon refexes; prominent anterior fontanel; seizure disorder; hepatomegaly; gastroesophageal reflux with pyloric stenosis; died at 9 months of age; deficient peroxisomal plasmalogen synthesis enzymes; amounts of c26:0 and c26:1 and the c26:0/c22:0 ratio are much higher than normal; phytanic acid oxidase is less than half of 1% of normal; donor subject is homozygous for a mutation in the splice-donor site of intron 2 in the PEX26 gene [c.230 +1,G>T (IVS2+1,G>T)], which leads to a frameshift at codon 77 and premature termination (T77fs139X) |
