Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_021139.3(UGT2B4):​c.1531T>G​(p.Cys511Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C511R) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: UGT2B4 NM_021139.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 3.09

Genes affected
