Intellectual disability - microarray and sequencing v3.1765 CACNA1I Eleanor Williams commented on gene: CACNA1I
Intellectual disability - microarray and sequencing v3.1765 CACNA1I Eleanor Williams Phenotypes for gene: CACNA1I were changed from Neurodevelopmental disorder to Neurodevelopmental disorder with speech impairment and with or without seizures, OMIM:620114
Intellectual disability - microarray and sequencing v3.1764 CACNA1I Eleanor Williams Tag gene-checked was removed from gene: CACNA1I.
Intellectual disability - microarray and sequencing v3.1564 CACNA1I Eleanor Williams Tag gene-checked tag was added to gene: CACNA1I.
Intellectual disability - microarray and sequencing v3.1519 CACNA1I Ivone Leong Tag Q4_21_rating was removed from gene: CACNA1I.
Intellectual disability - microarray and sequencing v3.1519 CACNA1I Sarah Leigh commented on gene: CACNA1I
Intellectual disability - microarray and sequencing v3.1519 CACNA1I Ivone Leong Source Expert Review Green was added to CACNA1I.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Intellectual disability - microarray and sequencing v3.1339 CACNA1I Ivone Leong Classified gene: CACNA1I as Amber List (moderate evidence)
Intellectual disability - microarray and sequencing v3.1339 CACNA1I Ivone Leong Added comment: Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is not associated with a phenotype in OMIM or Gene2Phenotype. There is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.
Intellectual disability - microarray and sequencing v3.1339 CACNA1I Ivone Leong Gene: cacna1i has been classified as Amber List (Moderate Evidence).
Intellectual disability - microarray and sequencing v3.1338 CACNA1I Ivone Leong Tag Q4_21_rating tag was added to gene: CACNA1I.

Review for gene: CACNA1I was set to GREEN
gene: CACNA1I was marked as current diagnostic
Added comment: 4 different missense variants identified and shown to result in a gain of function.

2 individuals with de novo variants (a 3rd also suspected de novo but their father was unavailable for testing) - these patients all had severe neurodevelopmental disorders, involving severe global developmental delay, absence of speech, gross motor delay, muscular hypotonia, early-onset seizures, cortical visual impairment, and feeding difficulties. Variable clinical features include various brain malformations, startle response or seizures, postnatal growth retardation, gastroesophageal reflux, and gastrostomy.

1 family had three affected individuals - variable cognitive impairment in all, involving borderline intellectual functioning or mild or moderate intellectual disability as main clinical feature, with late-onset seizures in the mother and speech retardation in one of the children. This variant had a milder functional effect than the variants in sporadic cases.
