A case report on holt-oram syndrome (heart-hand).

ABSTRACT:

Background

The Holt-Oram Syndrome (HOS) or the Heart-Hand syndrome is considered as an overt autosomal hereditary disease with a complete influential effect and variable expression that emerges due to a genetic mutation. It can be vividly characterized by heart disorders and deficiencies in hand structure. Despite the existing genetic heterogeneity, the variable integration between HOS and the T-BX5 gene from the T-BOX Gene Complex has been observed during which various mutations have been reported in the affected patients. The T-BOX Gene Complex is located on chromosome 12 (12 q 24.1), and is able to encode a copying factor. That has a conservative motive with 180 amino acids. The deficiencies in only 1/3 of patients have been observed caused by the mutation of this gene.
