ClinGen Rett and Angelman-like Disorders Variant Curation Expert Panel	RCV001800447	SCV002047340	benign	Rett syndrome	2021-12-13	reviewed by expert panel	curation	The allele frequency of the p.Ala447Thr (NM_004992.3) variant in MECP2 is 0.02% in East Asian sub population in gnomAD, which is high enough to be classified as likely benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BS1). The p.Ala447Thr variant is observed in at least 2 unaffected individuals (GeneDx internal database) (BS2). In summary, the p.Ala447Thr variant in MECP2 is classified as benign based on the ACMG/AMP criteria (BS1, BS2).
