Genes affected
PTTG1IP (HGNC:13524): (PTTG1 interacting protein) This gene encodes a single-pass type I integral membrane protein, which binds to pituitary tumor-transforming 1 protein (PTTG1), and facilitates translocation of PTTG1 into the nucleus. Coexpression of this protein and PTTG1 induces transcriptional activation of basic fibroblast growth factor. Alternatively spliced transcript variants have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.397G>A (p.E133K) alteration is located in exon 4 (coding exon 4) of the PTTG1IP gene. This alteration results from a G to A substitution at nucleotide position 397, causing the glutamic acid (E) at amino acid position 133 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
