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.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.11 is higher than 0.05.
