Genes affected

GRWD1 (HGNC:21270): (glutamate rich WD repeat containing 1) This gene encodes a glutamate-rich protein that contains five WD-repeat motifs. The encoded protein may play a critical role in ribosome biogenesis and may also play a role in histone methylation through interactions with CUL4-DDB1 ubiquitin E3 ligase.

Ambry Genetics

Oct 10, 2023

The c.697G>A (p.G233S) alteration is located in exon 5 (coding exon 5) of the GRWD1 gene. This alteration results from a G to A substitution at nucleotide position 697, causing the glycine (G) at amino acid position 233 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
