Genes affected
DDRGK1 (HGNC:16110): (DDRGK domain containing 1) The protein encoded by this gene interacts with components of the ubiquitin fold modifier 1 conjugation pathway and helps prevent apoptosis in ER-stressed secretory tissues. In addition, the encoded protein regulates nuclear factor-κB activity. [provided by RefSeq, Dec 2015]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2021The c.862C>T (p.R288W) alteration is located in exon 9 (coding exon 9) of the DDRGK1 gene. This alteration results from a C to T substitution at nucleotide position 862, causing the arginine (R) at amino acid position 288 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
