Quick Summary

Hallerman–Streiff–François syndrome is a rare genetic disorder characterized by premature aging (progeria) combined with dwarfism and other growth abnormalities. It is inherited as an autosomal-dominant trait. Individuals with this syndrome may exhibit underdevelopment of cheek and jaw bones, widely spaced eyes, malformed eyelids and ears, and absence of an external ear canal, leading to hearing loss. While intelligence is typically normal, respiratory issues can occur in newborns. Treatment may involve hearing aids or surgery for deafness and plastic surgery to address jaw underdevelopment.12
