#Marfan syndrome

• Acromacria — A rare congenital structural malformation or skeletal development anomaly characterized by the disproportionate, excessive length and thinning of the distal segments of the limbs, especially the digits.
• Arachnodactyly — A congenital anomaly characterized by the excessive length, slenderness, and unusual flexibility of the fingers and toes, causing them to assume an elongated appearance reminiscent of a spider's legs. It represents a major clinical sign and a foundational diagnostic criterion for hereditary connective tissue disorders, most frequently associated with Marfan syndrome or Loeys-Dietz syndrome.
