LAUSR

SHORT syndrome is a rare, multisystem disease named with the acronym arising from short stature, hyperextensibility of joints, ocular depression, Rieger anomaly, and teething delay. Metabolic anomalies such as insulin resistance and diabetes are also present. This disease is related to heterozygous variants in the PIK3R1 and is inherited in an autosomal-dominant manner. In this case report, we present a Taiwanese boy with SHORT syndrome who had growth retardation and dysmorphic features, including a triangular face, prominent forehead, and small chin. We performed anthropometric and laboratory measurements and imaging examinations. We noted no insulin resistance or diabetes. We performed whole exome and Sanger sequencing and confirmed the underlying genetic variant, detecting a heterozygous variant of PIK3R1 (NM_181523.3) (c.1945C > T). In a family survey, his parents indicated no similar clinical symptoms and no gene variant. This case is the first SHORT syndrome in Taiwan. Specific facial dysmorphisms of this case help us confirm the diagnosis with timely genetic testing and then we can provide appropriate management and proper care.
