18p-

18p- is a genetic condition where part of the short arm (p arm) of chromosome 18 is missing. This deletion can result in various health issues and developmental delays. Each case of 18p- is unique, and the symptoms and severity can vary greatly among individuals. Common challenges include developmental delays, often in the mild range, and potential health problems like heart defects, hormone issues, and neurological concerns. The condition is usually diagnosed through a blood test in infants or children exhibiting health and developmental concerns. The Chromosome 18 Registry & Research Society provides support and resources for families dealing with 18p-.
