Genetic Variant ZNF414:p.Ala354_Ala366dup (chr19-8510850-C-CCCGCGGGGGCGTCGGGGCGCGGCGGCCCGGCCGCGGGGG) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP3

The NM_001146175.2(ZNF414):c.1061_1099dupCCCCCGCGGCCGGGCCGCCGCGCCCCGACGCCCCCGCGG(p.Ala354_Ala366dup) variant causes a conservative inframe insertion, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000403 in 148,962 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. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.
