Wortmann et al (2017) PMID: 29205472 reclassified MEGDEL syndrome to MEGDHEL syndrome, 3-MEthylGlutaconic aciduria, Dystonia-Deafness, Hepatopathy, Encephalopathy, Leigh-like syndrome (MEGDHEL) as they found that liver involvement was an additional clinical feature, so Hepatopathy was incorporated into the acronym. From a study of 67 individuals (39 previously unreported) from 59 families were included (age range 5 days - 33.4 years, median age 9 years) Wortmann et al idenitified 41 different SERAC1 biallelic variants, including 20 that have not been reported before. With exception of two families with a milder phenotype, all affected individuals show a strikingly homogeneous phenotype and time course. Severe, reversible neonatal liver dysfunction and hypoglycemia was seen in more than 40% of all cases. Starting at a median age of six months muscular hypotonia (91%) was seen, followed by progressive spasticity (82%, median onset 15 months) and dystonia (82%, 18 months). The majority of affected individuals never learnt to walk (68%). 79% suffered hearing loss, 58% never learnt to speak, nearly all had significant intellectual disability (88%).
