Intellectual disability - microarray and sequencing v5.67 GRIA1 Achchuthan Shanmugasundram changed review comment from: Four different heterozygous variants in GRIA1 (p.Ala636Thr, p.Gly745Asp, p.Ile627Thr & p.Arg345Gln) have been identified in six unrelated individuals and they were all reported with intellectual disability, moderate to severe cognitive impairment, delayed motor development, speech impairment and behavioural issues such as anxiety, autism spectrum disorder and attention deficit hyperactivity disorder.

Homozygous variant (p.Arg377Ter) has been identified in one individual, who presented with intellectual disability, severe cognitive impairment, delayed motor development, speech impairment (non-verbal) and self-injurious behaviour.

In vitro functional studies with major GluA1-containing AMPAR subtypes carrying the GRIA1 variant mutations showed that three of the four missense variants profoundly perturb receptor function. The homozygous stop-gain variant completely destroyed the expression of GluA1-containing AMPARs. The Xenopus gria1 models also show transient motor deficits, an intermittent seizure phenotype, and a significant impairment to working memory in mutants.; to: Four different heterozygous variants in GRIA1 (p.Ala636Thr, p.Gly745Asp, p.Ile627Thr & p.Arg345Gln) have been identified in six unrelated individuals and they were all reported with intellectual disability, moderate to severe cognitive impairment, delayed motor development, speech impairment and behavioural issues such as anxiety, autism spectrum disorder and attention deficit hyperactivity disorder.

Intellectual disability - microarray and sequencing v3.678 GRIA1 Arina Puzriakova Classified gene: GRIA1 as Amber List (moderate evidence)
Intellectual disability - microarray and sequencing v3.678 GRIA1 Arina Puzriakova Added comment: Comment on list classification: Maintaining Amber rating as no new evidence has been published since previous review. Most commonly reported as a candidate gene in large screening studies with limited segregation/phenotype/functional data. Also variable penetrance of the ID phenotype. Therefore, there is currently not enough evidence to classify as Green.
