Core Tip

Core Tip: This report introduces a Chinese boy referred to our hospital mainly due to progressive postnatal microcephaly and intellectual disability with severe speech impairment. A novel pathogenic mutation (c.1795G>T; p.E599*) was detected in the patient by trio-based whole exome sequencing. The proband’s clinical features largely conformed to reported Bainbridge-Ropers syndrome patients in the literature. These clinical and genetic findings improved our understanding of Bainbridge-Ropers syndrome and also aided in the definitive diagnosis and genetic counseling for this family.
