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 edit
- Subtle feet anomalies such as syndactyly
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]
