Description

The p.T619I variant (also known as c.1856C>T), located in coding exon 14 of the POLD1 gene, results from a C to T substitution at nucleotide position 1856. The threonine at codon 619 is replaced by isoleucine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear.
