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]

The c.313C>T (p.R105C) alteration is located in exon 2 (coding exon 2) of the HIC1 gene. This alteration results from a C to T substitution at nucleotide position 313, causing the arginine (R) at amino acid position 105 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
