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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2023The c.637C>A (p.P213T) alteration is located in exon 4 (coding exon 4) of the PTCRA gene. This alteration results from a C to A substitution at nucleotide position 637, causing the proline (P) at amino acid position 213 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
