Description

The NOTCH2 c.6893G>A variant is predicted to result in the amino acid substitution p.Arg2298Gln. To our knowledge, this variant has not been reported in the literature. Of note, a different substitution at the same codon (p.Arg2298Trp) has been reported in an individual with congenital anomalies of the kidney and urinary tract (CAKUT), but the significance is unknown (van der Ven et al. 2018. PubMed ID: 30143558). This variant is reported in 0.022% of alleles in individuals of European (Non-Finnish) descent in gnomAD. In ClinVar, this variant is interpreted as uncertain/likely benign (https://preview.ncbi.nlm.nih.gov/clinvar/variation/291198/). This variant could be benign. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
