Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM4

The NM_001364171.2(ODAD1):​c.2029_2046dupGGAGGCCTCGGGTCCAGC​(p.Ser682_Arg683insGlyGlyLeuGlySerSer) variant causes a conservative inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,566 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Uncertain significance (★).

Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with CCDC114-related conditions. This variant is present in population databases (rs772407409, gnomAD 0.003%). This variant, c.1918_1935dup, results in the insertion of 6 amino acid(s) of the CCDC114 protein (p.Gly640_Ser645dup), but otherwise preserves the integrity of the reading frame. -
