GeneDx RCV000194285 SCV000170231 likely benign not specified 2017-10-24 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Integrated Genetics/Laboratory Corporation of America RCV000194285 SCV000917620 benign not specified 2018-07-06 criteria provided, single submitter clinical testing Variant summary: MECP2 c.1140G>A alters a conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no effect on splicing. The variant allele was found at a frequency of 6.5e-05 in 169949 control chromosomes, including 4 hemizygotes. The observed variant frequency is approximately 8-fold above the estimated maximal expected allele frequency for a pathogenic variant in MECP2 causing Rett Syndrome phenotype (8.3e-06), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.1140G>A in individuals affected with Rett Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign.
