Introduction
Uniparental disomy of chromosome 14, or UPD14, is a rare genetic condition characterized by the inheritance of both copies of chromosome 14 from one parent․ This can lead to various phenotypical features and neurologic disorders․
Overview of Uniparental Disomy of 14
Paternal uniparental disomy 14 (UPD(14)pat) is a severe form of the disorder affecting the 14q32․2 imprinted region, leading to distinctive phenotypical features․ Both copies of chromosome 14 inherited from one parent result in unique characteristics, such as polyhydramnios, craniofacial anomalies, thoracic, abdominal defects, and developmental delays․ Maternal uniparental disomy of chromosome 14 (upd(14)mat) presents a milder phenotype, often underdiagnosed due to the absence of specific congenital malformations, making it crucial for clinical recognition and genetic study․
Clinical Features
Distinct phenotypical features of paternal uniparental disomy 14 (UPD(14)pat) include polyhydramnios, craniofacial anomalies, thoracic, abdominal defects, and severe developmental delays․
