Genes affected
C8orf34 (HGNC:30905): (chromosome 8 open reading frame 34) This gene encodes a protein that is related to the cyclic AMP dependent protein kinase regulators. Naturally occurring mutations in this gene are associated with an increased risk for severe toxicities, such as diarrhea and neutropenia, in patients undergoing chemotherapeutic treatment.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.577A>G (p.I193V) alteration is located in exon 3 (coding exon 3) of the C8orf34 gene. This alteration results from a A to G substitution at nucleotide position 577, causing the isoleucine (I) at amino acid position 193 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
