Arina Puzriakova Added comment: Comment on mode of inheritance: Updated from 'monoallelic' only to 'both mono- and biallelic'. Biallelic variants cause a paediatric-onset leukodystrophy, with spasticity as a feature (MIM# 612233), while monoallelic variants have been associated with adult-onset HSP (MIM# 605280) - both phenotypes are relevant to this panel.
Arina Puzriakova Mode of inheritance for gene: HSPD1 was changed from MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
