---|---|---|---|---|---|---|
2012 | Metachromatic leukodystrophy (MLD) | Autosomal recessive | Eye,Nervous System,Muscle | Early Adult (both) | Late infantile MLD, the most common mutation is an ARSA splicing defect, c.465+1G>A, and for adult onset MLD the most common is c.1283C>T; together these mutations account for almost 33% of MLD alleles (Cesani et al., 2016) | 27638601 |
2013 | Mucopolysaccharidosis 6 (MPS6)/MAROTEAUXLAMY SYNDROME | Autosomal recessive | Ear,Eye,Heart,Bones,Liver,Spleen,Hair,Head,Nervous System | Early Adult (both) | p.Y251X: severe phenotype (Saudi Arabia), p.H178L is a common founder mutation found in Brazil, p.Y251X and c270_274del5bp pc.91Afs*34 genotypes , in consanguineous cases followed the rapidly severe phenotype. Cardiac involvement : p.R152W mutation in the ARSB gene. | 28914427 |
2018 | MPS type VII (Sly syndrome) | Autosomal recessive | Ear,Skin,Eye,Heart,Bones,Liver,Lungs,Hair,Nervous System,Kidney,Spleen | Early Adult (both) | Attenuated:p.C38G,p.D152G,p.L176F,p.K350N,p.S52F,p.R110X,p.P148S,p.E150K,Severe:p.K194fsX22,p.R216W,p.L243P,p.S312X,p.Y320S,Pseudodefeciency: p.D152N | 19224584 |
2019 | GM2gangliosidosis Tay-Sachs disease (HEXA) | Autosomal recessive | Nervous System,Lungs,Eye | Early Adult (both) | E482K: E482K is a buried residue important for a salt bridge with an arginine residue The change in charge of this residue likely explains the massive conformational changes predicted to occur. E482K and G269S ? mutants remain unprocessed and have impaired activities. G269S: adult-onset TSD, E482K mutant is a relatively rare variant, but a severe one that exhibits little residual activity and causes infantile forms of TSD82K: E482 is a buried residue important for a salt bridge with an arginine residue The change in charge of this residue likely explains the massive conformational changes predicted to occur. E482K and G269S ? mutants remain unprocessed and have impaired activities | 27682588 |
2034 | Batten Disease NCL 1 (CLN1) | Autosomal recessive | Nervous System,Bones,Head,Eye | Early Adult (both) | 49 mutations currently reported | 23747979 |
2037 | Galactosialidosis | Autosomal recessive | Nervous System,Bones,Skin,Heart,Ear | Early Adult (both) | p.Tyr413Cys mutation underlies the severe phenotype. The p.Tyr267Asn was detected in a variant form of an early infantile patient without neurological involvement.p.Gln67Arg was first reported in a juvenile patient, in combination with a mild mutation. Coarse facies, hepatosplenomegaly, growth retardation and an unusual renal symptomatology were described in a 9-year-old patient who was compound heterozygous for the p.Gly103Val and p.Arg442Trp mutations.p.Tyr413Cys, in the adult patient it was detected in combination with the c.746?+?3A > G change, reported as a mild mutation in homozygotes adult patients | 23915561 |
