Insights

Primary hyperoxaluria type 1 is a genetic kidney disease. A common AGXT gene mutation was found in three Indian children, highlighting the need for targeted genetic screening.

Area of Science:

  • Genetics
  • Nephrology
  • Biochemistry

Background:

  • Primary hyperoxaluria type 1 (PH1) is an inherited metabolic disorder.
  • It results from a deficiency in the AGXT gene, encoding alanine-glyoxylate aminotransferase.
  • PH1 leads to oxalate overproduction and kidney damage.

Observation:

  • Three Indian children with PH1 were studied.
  • All presented with chronic kidney disease (CKD).
  • A shared mutation in the AGXT gene was identified in all patients.

Findings:

  • The study identified a common AGXT gene mutation in three Indian children with PH1.
  • All affected children showed signs of CKD at diagnosis.
  • Progression to end-stage renal disease (ESRD) was observed in these patients.

Implications:

  • The findings suggest a specific AGXT mutation is prevalent in this Indian cohort.
  • Targeted genetic screening for this mutation could aid early PH1 diagnosis.
  • Early diagnosis and intervention may alter the course of kidney disease in PH1.

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
Pleiotropy01:33

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...

Protein Import into the Peroxisomes

Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...

Principles of Pharmacogenetics: Types of Genetic Variants

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
