Genes affected

TIAL1 (HGNC:11804): (TIA1 cytotoxic granule associated RNA binding protein like 1) The protein encoded by this gene is a member of a family of RNA-binding proteins, has three RNA recognition motifs (RRMs), and binds adenine and uridine-rich elements in mRNA and pre-mRNAs of a wide range of genes. It regulates various activities including translational control, splicing and apoptosis. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The different isoforms have been show to function differently with respect to post-transcriptional silencing. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.857T>C (p.V286A) alteration is located in exon 10 (coding exon 10) of the TIAL1 gene. This alteration results from a T to C substitution at nucleotide position 857, causing the valine (V) at amino acid position 286 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
