TBX5 Full Length Gene Sequence Analysis Holt-Oram Syndrome Test
At DNA Labs UAE, we offer the TBX5 Full Length Gene Sequence Analysis Holt-Oram Syndrome Test for individuals who suspect they may have Holt-Oram Syndrome (HOS). This test helps in the diagnosis and genetic counseling of affected individuals and their families.
Test Details
Holt-Oram Syndrome is an autosomal dominant disorder characterized by upper limb malformations and congenital heart defects. It is caused by mutations in the TBX5 gene, which plays a crucial role in limb and heart development.
The TBX5 gene is approximately 14 kilobases in length and consists of 9 exons. It encodes a protein of 518 amino acids with a molecular weight of 56.8 kDa. The protein contains a conserved DNA-binding domain called the T-box domain, which is essential for its function as a transcription factor.
Mutations in TBX5 can lead to various phenotypes associated with HOS, including absent or hypoplastic thumb, radial ray defects, and atrial septal defects. Most mutations are missense mutations, resulting in amino acid substitutions within the T-box domain, which impair the protein’s DNA-binding ability. Other types of mutations, such as frameshift, nonsense, and splice-site mutations, have also been reported.
Identification of TBX5 mutations is important for accurate diagnosis and genetic counseling. Our TBX5 Full Length Gene Sequence Analysis test can be performed using Sanger sequencing, next-generation sequencing, or multiplex ligation-dependent probe amplification (MLPA) methods.

Holt-Oram Syndrome (HOS) is an autosomal dominant disorder characterized by upper limb malformations and congenital heart defects. Mutations in the TBX5 gene, which encodes a transcription factor essential for limb and heart development, have been identified as the cause of HOS. The full-length gene sequence of TBX5 is approximately 14 kilobases in length and contains 9 exons. The gene encodes a protein of 518 amino acids with a molecular weight of 56.8 kDa. The protein contains a conserved DNA-binding domain, called the T-box domain, which is essential for its function as a transcription factor. Mutations in TBX5 can lead to a variety of phenotypes associated with HOS, including absent or hypoplastic thumb, radial ray defects, and atrial septal defects. The majority of mutations in TBX5 are missense mutations, which result in amino acid substitutions within the T-box domain that impair the protein’s DNA-binding ability. In addition to missense mutations, other types of mutations in TBX5 have also been reported, including frameshift, nonsense, and splice-site mutations. These mutations can result in premature termination of the protein or abnormal splicing of the mRNA, leading to a truncated or non-functional protein. Identification of TBX5 mutations in individuals with HOS is important for accurate diagnosis and genetic counseling. Genetic testing for TBX5 mutations can be performed using various methods, including Sanger sequencing, next-generation sequencing, and multiplex ligation-dependent probe amplification (MLPA). In summary, analysis of the full-length gene sequence of TBX5 is crucial for understanding the molecular basis of HOS and for accurate diagnosis and genetic counseling of affected individuals and their families. |
