Considering severity in the design of reproductive genetic carrier screening programs: screening for severe conditions.

Reproductive genetic carrier screening (RGCS) provides information about people's chance of having children with certain genetic conditions, to inform reproductive decision making. RGCS at population scale requires a robust and streamlined program that is purposively designed and formally implemented to ensure equity and consistency. There are many considerations in selecting conditions, genes and variants for inclusion in RGCS, with severity of the genetic condition a key criterion.

Views of healthcare professionals on the inclusion of genes associated with non-syndromic hearing loss in reproductive genetic carrier screening.

Genes associated with non-syndromic hearing loss (NSHL) are frequently included in panels for reproductive genetic carrier screening (RGCS), despite a lack of consensus on whether NSHL is a condition appropriate for inclusion in RGCS. We conducted a national online survey using a questionnaire to explore the views of clinicians who facilitate RGCS or provide care to deaf individuals in Australia and New Zealand regarding the inclusion of such genes in RGCS. Results were analysed descriptively, and free-text responses were analysed thematically.

New insights into carnitine-acylcarnitine translocase deficiency from 23 cases: Management challenges and potential therapeutic approaches.

Carnitine acyl-carnitine translocase deficiency (CACTD) is a rare autosomal recessive disorder of mitochondrial long-chain fatty-acid transport. Most patients present in the first 2 days of life, with hypoketotic hypoglycaemia, hyperammonaemia, cardiomyopathy or arrhythmia, hepatomegaly and elevated liver enzymes. Multi-centre international retrospective chart review of clinical presentation, biochemistry, treatment modalities including diet, subsequent complications, and mode of death of all patients.
