Genes affected

ZIC4 (HGNC:20393): (Zic family member 4) This gene encodes a member of the ZIC family of C2H2-type zinc finger proteins. Members of this family are important during development, and have been associated with X-linked visceral heterotaxy and holoprosencephaly type 5. This gene is closely linked to the gene encoding zinc finger protein of the cerebellum 1, a related family member on chromosome 3. Heterozygous deletion of these linked genes is involved in Dandy-Walker malformation, which is a congenital cerebellar malformation. Multiple transcript variants have been identified for this gene.

The c.1118C>G (p.A373G) alteration is located in exon 4 (coding exon 4) of the ZIC4 gene. This alteration results from a C to G substitution at nucleotide position 1118, causing the alanine (A) at amino acid position 373 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
