Comment:

The de novo GNAS c.380G>C (p.Arg127Thr) variant, to our knowledge, has not been reported in the medical literature. This variant is absent from the general population (gnomAD v.2.1.1), indicating it is not a common variant. Computational predictors indicate that the variant is damaging, evidence that correlates with impact to GNAS function. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time.
