GeneDx RCV000418787 SCV000536589 uncertain significance not provided 2017-01-30 criteria provided, single submitter clinical testing The c.4026 C>T (G1342G) variant in the CHD7 gene has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The variant was not observed in approximately 6,100 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This substitution occurs at a position that is not conserved. While this variant is a synonymous variant and does not result in a change to the CHD7 protein, several in silico splice prediction models predict that it creates a cryptic donor site which may supplant the natural donor site and lead to abnormal gene splicing. However, in the absence of RNA/functional studies, the actual effect of this sequence change is unknown. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
