Maternal heterozygosity of the Slc6a19 gene in mice leads to metabolic issues and congenital nicotinamide adenine dinucleotide (NAD) deficiency disorder. This research highlights the gene
Area of Science:
- Developmental Biology
- Genetics
- Metabolic Disorders
Background:
- Congenital malformations have complex genetic and environmental causes.
- The Slc6a19 gene plays a role in nutrient transport and metabolism.
- Nicotinamide adenine dinucleotide (NAD) is crucial for cellular energy and function.
Purpose of the Study:
- To investigate the impact of maternal Slc6a19 heterozygosity on offspring development and metabolism.
- To characterize the resulting congenital disorder in mice.
- To understand the link between Slc6a19 and NAD deficiency.
Main Methods:
- Mice models with maternal Slc6a19 heterozygosity were generated.
- Metabolic profiles and NAD levels were assessed in affected offspring.
- Genetic and biochemical analyses were performed.
Main Results:
- Maternal Slc6a19 heterozygosity caused significant metabolic perturbations in offspring.
- Affected mice exhibited congenital nicotinamide adenine dinucleotide (NAD) deficiency disorder.
- Slc6a19 deficiency was directly linked to impaired NAD synthesis or utilization.
Conclusions:
- Maternal Slc6a19 heterozygosity is a cause of congenital NAD deficiency disorder in mice.
- This finding reveals a novel genetic cause for congenital metabolic disorders.
- Understanding Slc6a19's role is critical for addressing developmental metabolic diseases.
Abstract:
First Person is a series of interviews with the first authors of a selection of papers published in Disease Models & Mechanisms, helping researchers promote themselves alongside their papers. Hartmut Cuny is first author on ' Maternal heterozygosity of Slc6a19 causes metabolic perturbation and congenital NAD deficiency disorder in mice', published in DMM. Hartmut is a senior postdoc in the lab of Prof. Sally Dunwoodie at Victor Chang Cardiac Research Institute, Sydney, Australia, investigating the genetic and environmental causes of congenital malformations.
