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.56G>T (p.G19V) alteration is located in exon 3 (coding exon 2) of the WDTC1 gene. This alteration results from a G to T substitution at nucleotide position 56, causing the glycine (G) at amino acid position 19 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
