This variant has been reported in 1 proband meeting Classic LFS criteria (PS4_Supporting; internal clinical contributor). This variant is absent in the gnomAD cohort (PM2_Supporting; http://gnomad.broadinstitute.org). There are 2 TP53 pathogenic variants (p.Y163C, p.A161D) previously reported at this codon (PM5; ClinVar ID 127814, 422295). In summary, the clinical significance of TP53 c.482_487del (p.Ala161_Tyr163delinsAsp) is uncertain for Li-Fraumeni syndrome. ACMG/AMP criteria applied, as specified by the TP53 Variant Curation Expert Panel: PM5, PM2_Supporting, PS4_Supporting.
