Classical Ehlers-Danlos syndrome with cranio-cervical instability in an infant due to a novel COL5A1 gene mutation.

Ehlers-Danlos syndromes (EDSs) are a group of connective tissue disorders with diverse clinical and genetic profiles. Classical Ehlers-Danlos syndrome (cEDS), the second most common type, is characterised by skin hyperextensibility, atrophic scars and joint hypermobility, primarily due to mutations in COL5A1 and COL5A2 genes. We report a case of an infant with severe cEDS presenting with motor developmental delay, joint hyperextensibility and cranio-cervical instability.
