Genes affected

NEIL3 (HGNC:24573): (nei like DNA glycosylase 3) NEIL3 belongs to a class of DNA glycosylases homologous to the bacterial Fpg/Nei family. These glycosylases initiate the first step in base excision repair by cleaving bases damaged by reactive oxygen species and introducing a DNA strand break via the associated lyase reaction (Bandaru et al., 2002 [PubMed 12509226]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.236T>G (p.L79W) alteration is located in exon 2 (coding exon 2) of the NEIL3 gene. This alteration results from a T to G substitution at nucleotide position 236, causing the leucine (L) at amino acid position 79 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
