Genes affected
DNTTIP2 (HGNC:24013): (deoxynucleotidyltransferase terminal interacting protein 2) This gene is thought to be involved in chromatin remodeling and gene transcription. The encoded nuclear protein binds to and enhances the transcriptional activity of the estrogen receptor alpha, and also interacts with terminal deoxynucleotidyltransferase. The expression profile of this gene is a potential biomarker for chronic obstructive pulmonary disease. [provided by RefSeq, Dec 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.1946A>C (p.K649T) alteration is located in exon 5 (coding exon 5) of the DNTTIP2 gene. This alteration results from a A to C substitution at nucleotide position 1946, causing the lysine (K) at amino acid position 649 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
