The ZNF699 c.1100_1101delAG variant is predicted to result in a frameshift and premature protein termination (p.Glu367Valfs*25). To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. This variant occurs within the last exon, however downstream protein truncating causative variants have been reported (Bertoli-Avella et al. 2021. PubMed ID: 33875846; Biela et al. 2022. PubMed ID: 35205213). Frameshift variants in ZNF699 are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
