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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 11, 2024The c.8956A>G (p.I2986V) alteration is located in exon 30 (coding exon 30) of the REV3L gene. This alteration results from a A to G substitution at nucleotide position 8956, causing the isoleucine (I) at amino acid position 2986 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
