Abstract
14q22q23 microdeletion syndrome, also called Frias syndrome, is an extremely rare partial deletion of the long arm of chromosome 14 characterized by the anomalies of the pituitary gland, eyes, and hand/foot. Intellectual disability and facial dysmorphism are other common manifestations. Haploinsufficiency of the genes bone morphogenetic protein 4 (BMP4) and orthodenticle homeobox 2 (OTX2) accounts for most of the phenotypic abnormalities seen in these patients. There are only a few cases reported with Frias syndrome in the literature, and there are multiple variations present, which are not well recognized due to different set of genes involved. This case report presents the case of a young child with a deletion in 14q22.2q23.1 region containing both BMP4 and OTX2 genes as well as sineoculis homeobox homolog 1 (SIX1) and sineoculis homeobox homolog 6 (SIX6) genes. The case report illustrates the wide phenotypic findings associated with these genes along with additional unique findings that previously have not been commonly reported.
