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]

The c.180C>A (p.F60L) alteration is located in exon 3 (coding exon 3) of the DNTTIP1 gene. This alteration results from a C to A substitution at nucleotide position 180, causing the phenylalanine (F) at amino acid position 60 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
