Genes affected
DNTTIP1 (HGNC:16160): (deoxynucleotidyltransferase terminal interacting protein 1) DNTTIP1 binds DNA and enhances the activity of terminal deoxynucleotidyltransferase (TDT, or DNTT; MIM 187410), a DNA polymerase that catalyzes the polymerization of DNA in the absence of a DNA template (Yamashita et al., 2001 [PubMed 11473582]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.11C>G (p.T4S) alteration is located in exon 1 (coding exon 1) of the DNTTIP1 gene. This alteration results from a C to G substitution at nucleotide position 11, causing the threonine (T) at amino acid position 4 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
