Variant 1-27297129-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2BP4BS2

The NM_001276252.2(WDTC1):c.1031G>A(p.Arg344Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00000342 in 1,460,272 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 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. R344W) has been classified as Uncertain significance.

Genes affected

WDTC1 (HGNC:29175): (WD and tetratricopeptide repeats 1) Predicted to enable enzyme inhibitor activity; histone binding activity; and histone deacetylase binding activity. Predicted to be involved in negative regulation of fatty acid biosynthetic process. Predicted to act upstream of or within several processes, including cellular response to insulin stimulus; glucose metabolic process; and negative regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. Predicted to be part of Cul4-RING E3 ubiquitin ligase complex. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.1028G>A (p.R343Q) alteration is located in exon 11 (coding exon 10) of the WDTC1 gene. This alteration results from a G to A substitution at nucleotide position 1028, causing the arginine (R) at amino acid position 343 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
