Genes affected

TESC (HGNC:26065): (tescalcin) Enables calcium ion binding activity. Involved in several processes, including cellular response to retinoic acid; positive regulation of macromolecule metabolic process; and positive regulation of myeloid cell differentiation. Located in several cellular components, including cytosol; lamellipodium; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.524C>T (p.P175L) alteration is located in exon 7 (coding exon 7) of the TESC gene. This alteration results from a C to T substitution at nucleotide position 524, causing the proline (P) at amino acid position 175 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
