Knowra 1p36 deletion syndrome 1p36 deletion syndrome 1p36 deletion syndrome is a genetic disorder caused by loss of genetic material from the short arm of chromosome 1. It commonly involves developmental delay, intellectual disability, and distinctive physical features.
Chromosome 1 : Chromosome 1 is the largest human chromosome and contains hundreds of genes. The syndrome results from missing material on its short arm.
Developmental delay : Developmental delay is slower-than-expected progress in one or more areas of childhood development. It is a frequent early concern in affected children.
Pediatric genetics : Pediatric genetics is the medical specialty that diagnoses and manages genetic conditions in children. Genetics specialists interpret deletion testing and coordinate care.
Angelman syndrome : Angelman syndrome is a neurogenetic disorder characterized by developmental impairment, limited speech, and distinctive behavior. Some developmental and behavioral features overlap, but its genetic mechanisms differ.
Chromosomal deletion : A chromosomal deletion is the loss of a segment of DNA from a chromosome. This genetic change defines the syndrome.
Intellectual disability : Intellectual disability is a neurodevelopmental condition involving limitations in intellectual functioning and adaptive behavior. It is a common long-term feature of the syndrome.
Genetic counseling : Genetic counseling helps people understand genetic conditions, testing, inheritance, and reproductive options. Counseling addresses recurrence risk and the meaning of test results.
Prader–Willi syndrome : Prader–Willi syndrome is a genetic disorder involving hypothalamic dysfunction, hypotonia, and often excessive appetite. Early hypotonia can resemble a feature of 1p36 deletion syndrome, though the causes differ.
1p36 : 1p36 is a band near the end of the short arm of chromosome 1. The deleted region includes this chromosome band.
Hypotonia : Hypotonia is abnormally low muscle tone, often affecting posture and movement. Low muscle tone can contribute to early motor difficulties.
