Genes affected

PTCRA (HGNC:21290): (pre T cell antigen receptor alpha) The protein encoded by this gene is a single-pass type I membrane protein that is found in immmature but not mature T-cells. Along with TCRB and CD3 complex, the encoded protein forms the pre-T-cell receptor complex, which regulates early T-cell development. Four transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]

Dec 01, 2022

The c.533C>T (p.P178L) alteration is located in exon 4 (coding exon 4) of the PTCRA gene. This alteration results from a C to T substitution at nucleotide position 533, causing the proline (P) at amino acid position 178 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
