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]

The c.1154A>T (p.N385I) 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 1154, causing the asparagine (N) at amino acid position 385 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
