Early onset or syndromic epilepsy v4.112 GRM7 Arina Puzriakova Tag Q2_23_promote_green was removed from gene: GRM7.
Early onset or syndromic epilepsy v4.110 GRM7 Arina Puzriakova reviewed gene: GRM7: Rating: GREEN; Mode of pathogenicity: ; Publications: ; Phenotypes: ; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Early onset or syndromic epilepsy v4.109 GRM7 Arina Puzriakova Source NHS GMS was added to GRM7.
Source Expert Review Green was added to GRM7.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Early onset or syndromic epilepsy v4.48 GRM7 Achchuthan Shanmugasundram changed review comment from: PMID:32286009 reported eleven individuals from six unrelated families identified with three different biallelic variants and presenting with a neurodevelopmental disorder comprising global developmental delay/ intellectual impairment, seizures, hypotonia, microcephaly and brain abnormalities. This is also supported by functional evidence from knockout mouse models, where absence of metabotropic glutamate receptor 7 alters the phenotypes within the domains of social behavior, associative learning, motor function, epilepsy and sleep (PMID:32248644).

This gene has also been associated with relevant phenotypes in both OMIM (MIM #618922) and in Gene2Phenotype (with 'strong' rating in the DD panel).; to: PMID:32286009 reported eleven individuals from six unrelated families identified with three different biallelic variants and presenting with a neurodevelopmental disorder comprising severe to profound global developmental delays, intellectual disability, seizures, hypotonia, microcephaly and brain abnormalities.

Early onset or syndromic epilepsy v4.48 GRM7 Achchuthan Shanmugasundram Classified gene: GRM7 as Amber List (moderate evidence)
Early onset or syndromic epilepsy v4.48 GRM7 Achchuthan Shanmugasundram Added comment: Comment on list classification: There is sufficient evidence (6 unrelated cases and supporting mouse model) for this gene to be promoted to GREEN at the next major update.
Early onset or syndromic epilepsy v4.48 GRM7 Achchuthan Shanmugasundram Gene: grm7 has been classified as Amber List (Moderate Evidence).
Early onset or syndromic epilepsy v4.47 GRM7 Achchuthan Shanmugasundram Phenotypes for gene: GRM7 were changed from Epilepsy, microcephaly, developmental delay to Neurodevelopmental disorder with seizures, hypotonia, and brain abnormalities, OMIM:618922
Early onset or syndromic epilepsy v4.46 GRM7 Achchuthan Shanmugasundram reviewed gene: GRM7: Rating: GREEN; Mode of pathogenicity: None; Publications: 32248644, 32286009; Phenotypes: Neurodevelopmental disorder with seizures, hypotonia, and brain abnormalities, OMIM:618922; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Early onset or syndromic epilepsy v2.89 GRM7 Zornitza Stark gene: GRM7 was added
gene: GRM7 was added to Genetic epilepsy syndromes. Sources: Literature
Mode of inheritance for gene: GRM7 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: GRM7 were set to 32286009; 32248644
Phenotypes for gene: GRM7 were set to Epilepsy, microcephaly, developmental delay
