Fetal anomalies v0.3685 GRIN2A Zornitza Stark Marked gene: GRIN2A as ready
Fetal anomalies v0.3685 GRIN2A Zornitza Stark Gene: grin2a has been classified as Red List (Low Evidence).
Fetal anomalies v0.3685 GRIN2A Zornitza Stark Phenotypes for gene: GRIN2A were changed from EPILEPSY WITH NEURODEVELOPMENTAL DEFECTS; LANDAU-KLEFFNER SYNDROME to Epilepsy, focal, with speech disorder and with or without mental retardation, MIM# 245570
Fetal anomalies v0.3684 GRIN2A Zornitza Stark Publications for gene: GRIN2A were set to
Fetal anomalies v0.3683 GRIN2A Zornitza Stark Mode of pathogenicity for gene: GRIN2A was changed from to Other
Fetal anomalies v0.3682 GRIN2A Zornitza Stark Mode of inheritance for gene: GRIN2A was changed from MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Fetal anomalies v0.3681 GRIN2A Zornitza Stark changed review comment from: Large cohort of 248 individuals reported in PMID: 30544257: The phenotypic spectrum ranged from normal or near-normal development with mild epilepsy and speech delay/apraxia to severe developmental and epileptic encephalopathy, often within the epilepsy-aphasia spectrum. Pathogenic missense variants in transmembrane and linker domains (misTMD+Linker) were associated with severe developmental phenotypes, whereas missense variants within amino terminal or ligand-binding domains (misATD+LBD) and null variants led to less severe developmental phenotypes. Other phenotypes such as MRI abnormalities and epilepsy types were also significantly different between the two groups. Notably, this was paralleled by electrophysiology data, where misTMD+Linker predominantly led to NMDAR gain-of-function, while misATD+LBD exclusively caused NMDAR loss-of-function.; to: Large cohort of 248 individuals reported in PMID: 30544257: The phenotypic spectrum ranged from normal or near-normal development with mild epilepsy and speech delay/apraxia to severe developmental and epileptic encephalopathy, often within the epilepsy-aphasia spectrum.
