There can be variations in the severity and combination of symptoms among individuals with this duplication.​ Early intervention and a comprehensive care plan involving specialists such as developmental pediatricians, geneticists, speech therapists, occupational therapists, and psychologists can help manage these symptoms and improve the quality of life for affected individuals.

Genetic Causes of Chromosome 14q Proximal Duplication

Chromosome 14q Proximal Duplication is typically caused by the presence of an extra segment of genetic material on the long arm (q) of chromosome 14.​ This additional genetic material can result from various genetic mechanisms٫ including non-allelic homologous recombination or unequal crossing over during meiosis٫ leading to an extra copy of genes in the duplicated region.​

In some cases, the duplication may be inherited from a parent who carries a balanced translocation involving chromosome 14, where part of chromosome 14 is exchanged with another chromosome.​ This balanced translocation may not cause any health issues for the parent but can lead to the duplication in their offspring.​

Spontaneous (de novo) duplications can also occur during early fetal development, where errors in cell division cause the extra genetic material to be duplicated on chromosome 14q.​ These de novo duplications are usually not inherited from parents and are unique to the affected individual.​

Understanding the genetic causes of Chromosome 14q Proximal Duplication is crucial for accurate diagnosis, genetic counseling, and potential future advancements in treatment options targeting the underlying genetic mechanisms involved in this condition.
