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

Nov 14, 2023

The c.389A>T (p.D130V) alteration is located in exon 3 (coding exon 3) of the GRWD1 gene. This alteration results from a A to T substitution at nucleotide position 389, causing the aspartic acid (D) at amino acid position 130 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
