Heart-hand syndrome, Spanish type, also known as heart-hand syndrome type 3 or III, is a very rare genetic disorder which is characterized by heart, hand, and sometimes feet abnormalities. It is a type of heart-hand syndrome,[2] a class of genetic disorders characterized by cardiac malformations and hand malformations. Only one family with the disorder has been reported in medical literature.[3]

Description

edit

People with this disorder have symptoms that affect the heart, hands and feet. These include:[4][5][6]

Heart

edit
  • Sick sinus
  • Bundle branch block

Hands

edit
  • Brachydactyly which resembles brachydactyly type C
  • Abnormal development of the middle phalanges of the fingers
  • Accessory ossicle on the proximal phalange of the index finger.

Feet

Etimology

edit

This condition was first discovered by Ruiz de la Fuente et al., when they described a 3-generation family from Spain with the symptoms mentioned above. The cardiac defects varied between family members; 3 members had intraventicular conduction defects and 1 had a sick sinus. In this family, the 2nd and 5th fingers were the most severely affected out of all the fingers. Autosomal dominant inheritance was suspected.[7]
