Genes affected
PTTG2 (HGNC:9691): (pituitary tumor-transforming 2) Predicted to enable SH3 domain binding activity. Predicted to be involved in homologous chromosome segregation and negative regulation of mitotic sister chromatid separation. Predicted to be located in cytoplasm. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
TBC1D1 (HGNC:11578): (TBC1 domain family member 1) TBC1D1 is the founding member of a family of proteins sharing a 180- to 200-amino acid TBC domain presumed to have a role in regulating cell growth and differentiation. These proteins share significant homology with TRE2 (USP6; MIM 604334), yeast Bub2, and CDC16 (MIM 603461) (White et al., 2000 [PubMed 10965142]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.283G>A (p.E95K) alteration is located in exon 1 (coding exon 1) of the PTTG2 gene. This alteration results from a G to A substitution at nucleotide position 283, causing the glutamic acid (E) at amino acid position 95 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
