It is not clear whether expression of CAMTA 1has been disrupted by this partial loss. Haploinsufficiency of CAMTA1is associated with autosomal dominant cerebellar dysfunction withv ariable cognitive and behavioral abnormalities (CECBA) (OMIM 614756), which is a neurologic disorder with significant phenotypic heterogeneity which may include global developmental delay of motor and language skills, mild intellectual disability, and behavioral andpsychiatric abnormalities such as autism and obsessive-compulsive disorder. Copy number losses similar to or smaller than the current interval have been reported in patients with phenotypes including global developmental delay, speech problems, learning disability, pervasive developmental disorder, ADHD, ataxic gait, and heart anomalies, all of which are neurobehavioral features observed in thec hromosome 1p36 deletion syndrome (OMIM 607872) (Mikhail 2011, Shim 2020, Thevenon 2012). There are no similar copy number losses of this region in the general populations of the Database of Genomic Variants. Thus, the clinical significance of this copy number variant (CNV) is pathogenic.
