Genes affected

TPRX1 (HGNC:32174): (tetrapeptide repeat homeobox 1) Homeobox genes encode DNA-binding proteins, many of which are thought to be involved in early embryonic development. Homeobox genes encode a DNA-binding domain of 60 to 63 amino acids referred to as the homeodomain. This gene is a member of the TPRX homeobox gene family. [provided by RefSeq, Jul 2008]

The c.803C>T (p.P268L) alteration is located in exon 2 (coding exon 2) of the TPRX1 gene. This alteration results from a C to T substitution at nucleotide position 803, causing the proline (P) at amino acid position 268 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
