Genes affected
POLI (HGNC:9182): (DNA polymerase iota) The protein encoded by this gene is an error-prone DNA polymerase involved in DNA repair. The encoded protein promotes DNA synthesis across lesions in the template DNA, which other polymerases cannot do. The encoded polymerase inserts deoxynucleotides across lesions and then relies on DNA polymerase zeta to extend the nascent DNA strand to bypass the lesion. [provided by RefSeq, May 2017]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.109T>A (p.S37T) alteration is located in exon 1 (coding exon 1) of the POLI gene. This alteration results from a T to A substitution at nucleotide position 109, causing the serine (S) at amino acid position 37 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
