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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2022The c.1133G>A (p.G378E) alteration is located in exon 2 (coding exon 2) of the TPRX1 gene. This alteration results from a G to A substitution at nucleotide position 1133, causing the glycine (G) at amino acid position 378 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
