Medium-chain acyl-CoA dehydrogenase deficiency


What is medium-chain acyl-CoA dehydrogenase deficiency (MCADD)?

About 1 in 10,000 babies born in the UK has MCADD. Babies with this inherited condition have problems breaking down fats to make energy for the body. This can lead to serious illness, or even death. Screening means that most babies who have MCADD can be recognised early, allowing special attention to be given to their diet, including making sure they eat regularly. This care can prevent serious illness and allow babies with MCADD to develop normally. Screening babies for MCADD is important because it enables those with the condition to be identified before they become suddenly and seriously ill.

MCADD parent information

A new page dedicated to making the parent information on MCADD more accessible is now available.

This page has all the documents needed for MCADD families, including the MCADD and your child leaflet, which is given to families after their baby has had a screen positive result for MCADD and they have had their first contact with health professionals (either their GP, paediatrician, midwife, health visitor or nurse specialist). It provides further information about MCADD, a step-by-step guide to how their child will be followed-up by health professionals, answers to some common questions, a place to record their own questions and details for their MCADD team and sources of further information and support.
