7-152648889-A-G

Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS1

The NM_005431.2(XRCC2):​c.596T>C​(p.Met199Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000316 in 1,614,164 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M199L) has been classified as Uncertain significance.

Genes affected
XRCC2 (HGNC:12829): (X-ray repair cross complementing 2) This gene encodes a member of the RecA/Rad51-related protein family that participates in homologous recombination to maintain chromosome stability and repair DNA damage. This gene is involved in the repair of DNA double-strand breaks by homologous recombination and it functionally complements Chinese hamster irs1, a repair-deficient mutant that exhibits hypersensitivity to a number of different DNA-damaging agents.

ACMG classification

Classification was made for transcript

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

BP4
Computational evidence support a benign effect (MetaRNN=0.105573624).
BP6
Variant 7-152648889-A-G is Benign according to our data. Variant chr7-152648889-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 182996.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000394 (6/152286) while in subpopulation EAS AF = 0.000964 (5/5186). AF 95% confidence interval is 0.00038. There are 0 homozygotes in GnomAd4. There are 4 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
