Intellectual disability v3.1482 ATAD1 Ivone Leong Publications for gene: ATAD1 were set to 28180185
Intellectual disability v3.185 ATAD1 Arina Puzriakova Tag treatable tag was added to gene: ATAD1.
Tag for-review tag was added to gene: ATAD1.
Intellectual disability v3.185 ATAD1 Arina Puzriakova Classified gene: ATAD1 as Amber List (moderate evidence)
Intellectual disability v3.185 ATAD1 Arina Puzriakova Added comment: Comment on list classification: Multiple affected individuals from 3 unrelated families. There is enough evidence for this gene to be rated GREEN at the next major review.
Intellectual disability v3.185 ATAD1 Arina Puzriakova Gene: atad1 has been classified as Amber List (Moderate Evidence).
Intellectual disability v3.184 ATAD1 Arina Puzriakova changed review comment from: Not associated with any phenotype in G2P. Pathogenic variants have been described in seven affected individuals (three distinct consanguineous families) including a homozygous nonsense (c.826G>T; p.Glu276*), frameshift (c.1070_1071delAT; p.His357Argfs*15), and missense (c.162G>C; p.Gln54His) variant in the ATAD1 gene. Patients present with severe neurological features of essentially total absence of psychomotor development, encephalopathy, extreme hypertonia, non-responsiveness to stimuli, and death within the first few months of life. ; to: Not associated with any phenotype in G2P.

Pathogenic variants have been described in seven affected individuals (three distinct consanguineous families) including a homozygous nonsense (c.826G>T; p.Glu276*), frameshift (c.1070_1071delAT; p.His357Argfs*15), and missense (c.162G>C; p.Gln54His) variant in the ATAD1 gene. Patients present with severe neurological features of essentially total absence of psychomotor development, encephalopathy, extreme hypertonia, non-responsiveness to stimuli, and death within the first few months of life.

Knockout mouse model recapitulates phenotype. ATAD1 encodes Thorase, a mediator of AMPA receptor recycling; and therefore it was postulated that pathogenesis is a result of excessive AMPA receptor activity. Targeted therapy using perampanel, an AMPA receptor antagonist, ameliorated disease in both mice and humans, thus further supporting the role of ATAD1.
