Genes affected

TESPA1 (HGNC:29109): (thymocyte expressed, positive selection associated 1) Predicted to enable phospholipase binding activity. Predicted to be involved in several processes, including COP9 signalosome assembly; positive regulation of T cell differentiation in thymus; and positive regulation of T cell receptor signaling pathway. Predicted to act upstream of or within TCR signalosome assembly. Part of COP9 signalosome. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Sep 16, 2021

The c.740A>T (p.Q247L) alteration is located in exon 9 (coding exon 8) of the TESPA1 gene. This alteration results from a A to T substitution at nucleotide position 740, causing the glutamine (Q) at amino acid position 247 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
