Rebecca Foulger commented on gene: MTR: PMID:9683607 (Wilson et al., 1998) report 3 cblG patients, including 2 siblings who presented with neonatal seizures.
Rebecca Foulger commented on gene: MTR: PMID:25526710 (Huemer et al., 2015) summarise clinical features of 13 patients with the cblG defect (caused by defects in MTR): 5/13 had seizures.
Louise Daugherty Phenotypes for gene: MTR were changed from Homocystinuria-megaloblastic anemia, cblG complementation type, 250940; seizures to Homocystinuria-megaloblastic anemia, cblG complementation type, 250940; methionine synthase deficiency type cblG; seizures
Rebecca Foulger Added comment: Comment on list classification: Updated rating from Amber to Green: Green review by Zornitza plus sufficient (>3) cases of cblC disease patients with MMACHC variants and seizures from PMIDs 17431913 and 20924684).
Rebecca Foulger commented on gene: MMACHC: PMID:20924684 (Wang et al, 2010) report 43 patients with combined methylmalonic acidemia and hyperhomocysteinemia (cblC type), 50% of which presented with seizures. Homozygous MMACHC variants are listed in Table 4.
Ivone Leong Phenotypes for gene: HCFC1 were changed from Mental retardation, X-linked 3 (methylmalonic acidemia and homocysteinemia, cblX type ), 309541 to Mental retardation, X-linked 3 (methylmalonic acidemia and homocysteinemia, cblX type), 309541
