Genes affected

LIG1 (HGNC:6598): (DNA ligase 1) This gene encodes a member of the ATP-dependent DNA ligase protein family. The encoded protein functions in DNA replication, recombination, and the base excision repair process. Mutations in this gene that lead to DNA ligase I deficiency result in immunodeficiency and increased sensitivity to DNA-damaging agents. Disruption of this gene may also be associated with a variety of cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

The c.2743C>T (p.P915S) alteration is located in exon 28 (coding exon 27) of the LIG1 gene. This alteration results from a C to T substitution at nucleotide position 2743, causing the proline (P) at amino acid position 915 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
