Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4BP6_ModerateBS1

The NM_013975.4(LIG3):​c.452G>A​(p.Arg151Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000335 in 1,614,046 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R151W) has been classified as Uncertain significance.

Genes affected
LIG3 (HGNC:6600): (DNA ligase 3) This gene is a member of the DNA ligase family. Each member of this family encodes a protein that catalyzes the joining of DNA ends but they each have a distinct role in DNA metabolism. The protein encoded by this gene is involved in excision repair and is located in both the mitochondria and nucleus, with translation initiation from the upstream start codon allowing for transport to the mitochondria and translation initiation from a downstream start codon allowing for transport to the nucleus. Additionally, alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
LIG3 Gene-Disease associations (from GenCC):
  • mitochondrial DNA depletion syndrome 20 (mngie type)

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.31556827).
BP6
Variant 17-34983457-G-A is Benign according to our data. Variant chr17-34983457-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 933155.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.0000591 (9/152200) while in subpopulation AMR AF = 0.000458 (7/15292). AF 95% confidence interval is 0.000215. There are 0 homozygotes in GnomAd4. There are 3 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
