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.

Collection Method: clinical testing

The c.1612C>T (p.R538W) alteration is located in exon 2 (coding exon 2) of the ZIC5 gene. This alteration results from a C to T substitution at nucleotide position 1612, causing the arginine (R) at amino acid position 538 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
