The p.Glu117GlyfsTer88 variant is novel (not in any individuals) in 1000 Genomes and has allele frequency of 2.18% in gnomAD database. This variant has not been reported to the ClinVar database. This variant causes a frameshift starting with codon Glutamic Acid 117, changes this amino acid to Glycine residue, and creates a premature Stop codon at position 88 of the new reading frame, denoted p.Glu117GlyfsTer88. For these reasons, this variant has been classified as Likely Pathogenic. In the absence of another reportable variant the molecular diagnosis is not confirmed.

Comment:

The CEP164 c.347dupA variant is predicted to result in a frameshift and premature protein termination (p.Glu117Glyfs*88). To our knowledge, this variant has not been reported in the literature. This variant is reported in 3.1% of alleles in individuals of South Asian descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
