Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP7

The NM_001007527.2(LMBRD2):​c.60G>C​(p.Leu20Leu) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as (no stars). Synonymous variant affecting the same amino acid position (i.e. L20L) has been classified as Uncertain significance.
