GeneDx RCV000188467 SCV000242081 uncertain significance not provided 2012-06-20 criteria provided, single submitter clinical testing p.Gly28Glu (GGG>GAG): c.83 G>A in exon 2 of the PNKP gene (NM_007254.2) The Gly28Glu missense change has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The NHLBI ESP Exome Variant Project has not identified Gly28Glu in approximately 5,000 individuals of European or African American ethnicity, indicating that it is not a common benign variant in these populations. The amino acid change is non-conservative, as an uncharged, non-polar Glycine is replaced by a negatively charged Glutamic acid residue. It alters a position in the FHA domain of the PNKP protein that is highly conserved across species but is not conserved in related proteins, and multiple in silico algorithms predict Gly28Glu is not pathogenic. Therefore, based on the currently available information, it is unclear whether Gly28Glu is a disease-causing mutation or a rare benign variant. The variant is found in INFANT-EPI panel(s).
