Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant has not been reported in the literature but is present in the Genome Aggregation Database (Highest reported MAF 0.01% (6/53144) including 2 hemizygotes (https://gnomad.broadinstitute.org/variant/X-74740219-C-T?dataset=gnomad_r3). This variant is present in ClinVar, with multiple labs classifying this variant as Likely Benign (Variation ID:435594). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. Of note, this variant is a silent variant and does not change the amino acid, reducing the probability that this variant is disease causing. In summary, data on this variant suggests that this variant does not cause disease but requires further evidence. Therefore, this variant is classified as likely benign. -
