Eur J Med Genet 2024; 71:104962. [PMID: 39069255 DOI: 10.1016/j.ejmg.2024.104962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 07/09/2024] [Accepted: 07/25/2024] [Indexed: 07/30/2024]
Abstract
The spectrum of UDP-glucuronosyltransferase (UGT1A1) variants, which are associated with Gilbert syndrome (GS) and Crigler-Najjar syndrome (CNS-II), has been reported in Chinese and western countries. However, the genotype-phenotype correlation of the individual UGT1A1 variants in GS and CNS-II remains to be clarified. To explore the UGT1A1 variant pattern and genotype-phenotype correlations, we enrolled 310 Chinese patients, including 232 patients with GS and 78 with CNS-II. Peripheral blood samples were collected for screening variants in the gene UGT1A1 by a polymerase chain reaction and Sanger sequencing. The correlation between different UGT1A1 variants and clinical phenotypes was analyzed. A total of 21 UGT1A1 variants were identified, including nine novel variants, and constituted 42 UGT1A1 genotypes in the GS and CNS-II patients. The most common UGT1A1 variants were A (TA)7TAA, p.G71R, p.Y486D, p.P364L, and p.P229Q, which were different from western countries. The p.Y486D variant had higher minor allele frequency in CNS-II than in GS whereas the A (TA)7TAA variant had higher minor allele frequency in GS than in CNS-II. The serum total bilirubin and triglyceride had significant differences among 14 recurrent genotypes of UGT1A1, in which the serum total bilirubin in patients with compound p.Y486D (homozygous)/p.G71R variant was significantly higher compared with homozygous A (TA)7TAA, homozygous p.G71R, compound heterozygous A (TA)7TAA/p.G71R and A (TA)7TAA/p.P364L, and combined heterozygous A (TA)7TAA/p.G71R/p.P229Q, while the serum triglyceride in patients with combined A (TA)7TAA (homozygous)/p.P229Q variant was significantly higher compared with compound heterozygous A (TA)7TAA/p.G71R, single heterozygous A (TA)7TAA, single heterozygous p.G71R, and homozygous A (TA)7TAA. The spectrum of UGT1A1 genotypes in Chinese patients was distinct from western countries. There were differential levels of serum total bilirubin and triglyceride in patients with recurrent genotypes of UGT1A1.

Wen W, Yin D, Huang F, Guo M, Tian T, Zhu H, Yang Y. NGS in argininosuccinic aciduria detects a mutation (D145G) which drives alternative splicing of ASL: a case report study. BMC MEDICAL GENETICS 2016; 17:9. [PMID: 26843370 PMCID: PMC4739340 DOI: 10.1186/s12881-016-0273-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/09/2015] [Accepted: 01/29/2016] [Indexed: 12/30/2022]
Abstract
BACKGROUND Argininosuccinic aciduria (ASAuria; OMIM 207900) is a rare autosomal recessive heterogeneous urea cycle disorder, which leads to the accumulation of argininosuccinic acid in the blood and urine. We aimed to perform genetic test to the patient and help clinician to diagnose precisely. CASE PRESENTATION In this study, we use next generation sequencing (NGS) and exon trapping to analysis the family members. We identified compound heterozygous mutations of the argininosuccinate lyase (ASL) gene in a Chinese Han ASAuria patient. The c.434A>G (p.(D145G)) mutation in exon 5 was shown by exon trapping to select for the formation of an alternative transcript deleted for exon 5. The c.1366C>T (p.(R456W)) mutation had been previously reported in an Italian patient. CONCLUSIONS This is the first report of a missense mutation driving alternative splicing which results in the loss of exon 5 in ASAuria. This study also demonstrates the value of NGS in the identification of mutations and molecular diagnosis for ASAuria families.
