Variant 17-2057556-G-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_006497.4(HIC1):c.866G>T(p.Arg289Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000173 in 1,500,112 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R289H) has been classified as Uncertain significance.

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

Nov 21, 2023

The c.923G>T (p.R308L) alteration is located in exon 2 (coding exon 2) of the HIC1 gene. This alteration results from a G to T substitution at nucleotide position 923, causing the arginine (R) at amino acid position 308 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
