-

The stop gained variant has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is novel (not in any individuals) in gnomAD Exomes and in 1000 Genomes. This variant is predicted to cause loss of normal protein function through protein truncation. Loss of function variants have been previously reported to be disease causing. For these reasons, this variant has been classified as Likely Pathogenic. -
