Approximately one in five individuals with a 16p11.2 duplication are diagnosed with autism spectrum disorder, a condition that impacts social and communication abilities. Additionally, there is a higher chance of mental health issues among affected people, such as sadness, anxiety, and schizophrenia.
Clinically significant symptoms of these two conditions commonly co-occur, and children with both sets of symptoms may respond poorly to standard ADHD treatments. Individuals with autism spectrum disorder may benefit from additional types of medications. [13] [14] The term AuDHD is sometimes used for those with both autism and ADHD.
16p11.2 deletion syndrome is a rare genetic condition caused by microdeletion on the short arm of chromosome 16. Most affected individuals experience global developmental delay and intellectual disability, as well as childhood-onset obesity. [1] 16p11.2 deletion is estimated to account for approximately 1% of autism spectrum disorder cases. [3] [4]
Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells. The shorter arm (p arm) is termed 11p while the longer arm (q arm) is 11q.
Identical twin studies put autism's heritability in a range between 36% and 95.7%, with concordance for a broader phenotype usually found at the higher end of the range. [28] Autism concordance in siblings and fraternal twins is anywhere between 0 and 23.5%. This is more likely 2–4% for classic autism and 10–20% for a broader spectrum.
There is no specific medication for ASD, however, drugs can be prescribed for other co-existing mental health conditions, such as anxiety. A study in 2019 found that the management of challenging behaviors was generally of low quality, with little support for long-term usage of psychotropic drugs, and concerns about their inappropriate ...
The organization centers itself on “research, advocacy, empathy and unity” in an effort to raise awareness and funds for those in the autism community. For Kylie, the foundation’s mission is ...
Fragile X syndrome co-occurs with autism in many cases and is a suspected genetic cause of the autism in these cases. [ 12 ] [ 23 ] This finding has resulted in screening for FMR1 mutation to be considered mandatory in children diagnosed with autism. [ 12 ]
