Abstract
The PIK3CA-related overgrowth spectrum (PROS) encompasses a group of rare disorders characterized by the overgrowth of various body parts, driven by mutations in the PIK3CA gene. This study presents a case of a Moroccan female patient with PROS, demonstrating a phenotype associated with genetic mosaicism in the PIK3CA gene. A multidisciplinary approach, involving clinical examination, radiological assessment, and genetic and bioinformatic analyses, was employed for diagnosis and management. Next-generation sequencing and Sanger sequencing identified a rare variant, c.353G>A, in exon 3 of the PIK3CA gene, not detected in leukocyte DNA but confirmed in tissue biopsy samples. The comprehensive analysis of this case furthers our understanding of PROS and highlights the importance of a multidisciplinary approach to the diagnosis and management of this rare disorder.
