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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.815G>A (p.R272Q) alteration is located in exon 9 (coding exon 8) of the TESPA1 gene. This alteration results from a G to A substitution at nucleotide position 815, causing the arginine (R) at amino acid position 272 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
