Genes affected

HIC1 (HGNC:4909): (HIC ZBTB transcriptional repressor 1) This gene functions as a growth regulatory and tumor repressor gene. Hypermethylation or deletion of the region of this gene have been associated with tumors and the contiguous-gene syndrome, Miller-Dieker syndrome. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Sep 2010]

Ambry Genetics

Jan 03, 2024

The c.56C>A (p.T19K) alteration is located in exon 2 (coding exon 2) of the HIC1 gene. This alteration results from a C to A substitution at nucleotide position 56, causing the threonine (T) at amino acid position 19 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
