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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.680T>A (p.I227N) alteration is located in exon 2 (coding exon 2) of the TPRX1 gene. This alteration results from a T to A substitution at nucleotide position 680, causing the isoleucine (I) at amino acid position 227 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
