| Gene |
UGT1A1 |
| Chromosomal Location |
2q37 |
| Allelic Variant 1 |
191740.0002; CRIGLER-NAJJAR SYNDROME, TYPE I |
| Identified Mutation |
SER376PHE; In 2 first cousins from a consanguineous family with Crigler-Najjar syndrome type I, Erps et al. [J. Clin. Invest. 93: 564-570 (1994)] identified a C-to-T transition in the second position of codon 376, predicting a change of serine to phenylalanine in all UGT1-encoded UDPGTs, including the primary bilirubin UDPGT isoform. The patients were homozygous for the mutation. |

| Remarks |
First cousin of GM09218; persistent unconjugated hyperbilirubinemia; no evidence of neurologic or cognitive impairment; parents are third cousins; the donor subject is homozygous for a C-to-T transition (TCC>TTC) in exon 4 of the UGT1A1 gene which results in a substitution of phenylalanine for serine at codon 376 [SER376PHE (S376F)]. |
