Insights

Mutations in ATP-binding cassette (ABC) transporter genes ABCC6 and ABCA12 cause distinct skin diseases. This discovery impacts genetic diagnosis and prenatal testing for these conditions.

Area of Science:

  • Genetics
  • Molecular Biology
  • Dermatology

Background:

  • ATP-binding cassette (ABC) superfamily genes encode transmembrane proteins crucial for cellular transport.
  • Mutations in ABC transporters are linked to various human diseases.
  • Two specific ABC genes, ABCC6 and ABCA12, are implicated in skin disorders.

Purpose of the Study:

  • To highlight the role of ABC transporter gene mutations in human diseases.
  • To demonstrate the phenotypic diversity associated with mutations in ABCC6 and ABCA12.
  • To underscore the implications for genetic diagnostics in related disorders.

Main Methods:

  • Review of genetic studies on ABC transporter genes.
  • Analysis of mutation data for ABCC6 and ABCA12.
  • Correlation of genotype with clinical phenotypes.

Main Results:

  • Mutations in ABCC6 cause pseudoxanthoma elasticum.
  • Mutations in ABCA12 cause harlequin ichthyosis.
  • These findings reveal a spectrum of ABC gene-related skin diseases.

Conclusions:

  • ABC gene mutations are significant contributors to inherited skin conditions.
  • Understanding these mutations is vital for accurate genetic diagnosis.
  • The findings facilitate DNA-based prenatal testing and pre-implantation genetic diagnosis for affected families.

ABC Transporters: Exporter01:31

ABC Transporters: Exporter

ATP-binding cassette or ABC transporter is the largest superfamily of integral membrane proteins. The transporters have transmembrane-binding domains (TMDs) and nucleotide-binding domains (NBDs). The TMDs are specific to their substrates, whereas the NBDs are similar to engines that complete ATP hydrolysis to complete the substrate transport. They can be full transporters consisting of two TMDs and NBDs, half transporters with one TMD and NBD, while some encoded with a single TMD or NBD are...
ABC Transporters: Importer01:27

ABC Transporters: Importer

ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into importers and exporters. While exporters are present in all domains of life, importers exist only in bacteria and some plants.
In bacteria, based on the number of transmembrane helices and the chemical nature of their substrates, the ABC importers can be divided into three types:
Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters01:16

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...
ATP Driven Pumps I: An Overview01:27

ATP Driven Pumps I: An Overview

ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic side and the ion-conducting domain in the transmembrane region. These pumps use the free energy released from ATP hydrolysis to move the solutes across cell membranes against an electrochemical gradient.
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and are...
The Significance of Membrane Transport01:44

The Significance of Membrane Transport

The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action potential, exchanging nutrients and gases, etc. Membrane transport can be either passive or active. It can be simple diffusion, facilitated, or mediated transport aided by transport proteins such as transporters and channels.
Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
