• rs3218592
• NM_001372078.1:c.8285G>T

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_001372078.1(REV3L):​c.8285G>T​(p.Arg2762Leu) variant causes a missense change. 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. R2762Q) has been classified as Benign.

Genes affected

REV3L (HGNC:9968): (REV3 like, DNA directed polymerase zeta catalytic subunit) The protein encoded by this gene represents the catalytic subunit of DNA polymerase zeta, which functions in translesion DNA synthesis. The encoded protein can be found in mitochondria, where it protects DNA from damage. Defects in this gene are a cause of Mobius syndrome. [provided by RefSeq, Jan 2017]

MFSD4B (HGNC:21053): (major facilitator superfamily domain containing 4B) Predicted to enable glucose transmembrane transporter activity. Predicted to be involved in glucose transmembrane transport and sodium ion transport. Predicted to be located in apical plasma membrane. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
