Clinical Genomics Laboratory, Washington University in St. Louis RCV003457221 SCV004177113 uncertain significance Cardiofaciocutaneous syndrome 3 2023-10-26 criteria provided, single submitter clinical testing A MAP2K1 c.1023-4T>A variant was identified at a near heterozygous allelic fraction of 49%, which may be consistent with germline origin. To our knowledge, this variant has not been reported in the medical literature in relation to MAP2K1-related disease. This variant is only observed on 2/152,174 alleles in the general population (gnomAD v.3.1.2), indicating it is not a common variant. Computational predictors indicate that the variant has no impact on splicing, evidence that this variant may not have a damaging effect on MAP2K1 function. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868) and based on ClinGen's RASopathy expert panel (Gelb BD et al. PMID: 29493581), the clinical significance of this variant is uncertain at this time.
