| Remarks |
Hypotonia; seizures; macrocephalic; expired at age 5 months; deficient peroxisomal B-oxidation in fibroblasts; slightly abnormal phytanic acid oxidation in fibroblasts; elevated levels of trihydroxycholestanoic acid (THCA) in plasma; donor subject is homozygous for a deletion of 2 bp at position 422_423 of the HSD17B4 (D-BP) gene cDNA causing a frameshift leading to a premature stop codon at position 490, which results in a shortened product of 163 amino acids; the inactive protein lacks the catalytic aa tyrosine and lysine in the NYSAAK-motif characteristics of the short-chain-alcohol dehydrogenase gene family |
