Analysis of the 5.8S rRNA and internal transcribed spacers regions of the variant Naegleria fowleri Thai strain.

The aim of this study was to analyze the internal transcribed spacers regions (ITS) of the of 5.8S ribosomal RNA (rRNA) gene of four isolants of Naegleria fowleri. Three of four Thai strains were isolated from patients and one from the environment.

A de novo R589C mutation of anion exchanger 1 causing distal renal tubular acidosis.

Anion exchanger 1 (AE1 or SLC4A1) mutations have been reported to cause distal renal tubular acidosis (dRTA), a disease characterized by impaired acid excretion in the distal nephron. We have recently demonstrated homozygous AE1 G701D mutation as a common molecular defect of autosomal recessive (AR) dRTA in a group of Thai pediatric patients. In the present work, we discovered a de novo heterozygous AE1 R589C mutation, previously documented in inherited autosomal dominant (AD) dRTA.

A novel fluorescent quadruplex STR typing system and the allele frequency distributions in a Thai population.

We have previously reported a new triplex amplification and typing system by silver staining for three short tandem repeat (STR) loci, 9q2h2 (D2S3020), D15S233, and D14S299 without "microvariant" alleles such as .1, .2, and, .

Successful bone marrow transplantation in a child with red blood cell pyruvate kinase deficiency.

We report the first successful use of BMT for the treatment of RBC pyruvate kinase (PK) deficiency in a boy who developed neonatal jaundice and severe transfusion-dependent hemolytic anemia a few months after birth. He received a BMT at the age of 5 from an HLA-identical sister who has normal PK activity after conditioning with busulfan and cyclophosphamide. The post-transplant course was uneventful.
