Abstract:
The syndrome of ataxia-pancytopenia is an autosomal dominant disorder characterized by cerebellar ataxia, peripheral neuropathies, pancytopenia and a predilection to myelodysplastic syndrome and acute myeloid leukemia. The genetic basis of this condition is unknown. We describe a child who presented with ataxia and pancytopenia and was found to have a heterozygous mutation, c.845G>A (Arg282His) in TINF2, a gene recently reported to be mutated in a subset of patients with autosomal dominant dyskeratosis congenita. We propose that some cases of ataxia-pancytopenia may be affected by DC.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
