Genetic Variant VEZF1:p.Gln343_Gln349dup (chr17-57979243-T-TTGCTGCTGCTGCTGCTGCTGC) – ACMG Classification: Likely_benign (-5 pts)

Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP3BS2

The NM_007146.3(VEZF1):c.1026_1046dupGCAGCAGCAGCAGCAGCAGCA(p.Gln343_Gln349dup) variant causes a disruptive inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000119 in 150,648 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. Synonymous variant affecting the same amino acid position (i.e. Q349Q) has been classified as Likely benign.

Genes affected

VEZF1 (HGNC:12949): (vascular endothelial zinc finger 1) Transcriptional regulatory proteins containing tandemly repeated zinc finger domains are thought to be involved in both normal and abnormal cellular proliferation and differentiation. ZNF161 is a C2H2-type zinc finger protein (Koyano-Nakagawa et al., 1994 [PubMed 8035792]). See MIM 603971 for general information on zinc finger proteins.[supplied by OMIM, Sep 2008]
