Department of Pathology and Laboratory Medicine, Sinai Health System	RCV001353840	SCV000592358	likely benign	Endometrial carcinoma		no assertion criteria provided	clinical testing	The p.Gln146Gln variant has not been previously reported in the literature, public or private databases, nor by our laboratory. This variant is not expected to have clinical significance because it does not alter an amino acid residue and is not located near a splice junction. In summary, based on the limited amount of information, the clinical significance of this variant could not be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as predicted benign.
