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]

The c.8541C>G (p.D2847E) alteration is located in exon 28 (coding exon 28) of the REV3L gene. This alteration results from a C to G substitution at nucleotide position 8541, causing the aspartic acid (D) at amino acid position 2847 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
