Abstract:	We present a 19-year-old male with laxity of skin and joints, sparse scalp hair, facial dysmorphism, epilepsy, multiple exostoses, scoliosis, gastroesophageal reflux, cardiovascular defects, and an 8q23.3–q24.22 deletion detected by array comparative genomic hybridization. The patient was previously misdiagnosed as having Ehlers–Danlos syndrome. However, his clinical findings are in fact correlated with trichorhinophalangeal syndrome type II/Langer–Giedion syndrome and Cornelia de Lange syndrome-4. We discuss the genotype–phenotype correlation and the consequence of haploinsufficiency of TRPS1, RAD21, EXT1 and KCNQ3 in this case.
