Variant summary

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

The NM_033132.5(ZIC5):​c.1170_1190dupGCCGCCGCCGCCGCCGCCGCC​(p.Pro391_Pro397dup) variant causes a disruptive inframe insertion change involving the alteration of a non-conserved nucleotide. 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.

Genes affected
ZIC5 (HGNC:20322): (Zic family member 5) This gene encodes a member of the ZIC family of C2H2-type zinc finger proteins. The encoded protein may act as a transcriptional repressor. Studies in mouse and Xenopus support a role for this gene in neural crest development. Elevated expression of this gene has been observed in various human cancers and may contribute to cancer progression. This gene is closely linked to a related family member on chromosome 13.
