Genes affected
ACSM3 (HGNC:10522): (acyl-CoA synthetase medium chain family member 3) Enables butyrate-CoA ligase activity. Predicted to be involved in acyl-CoA metabolic process and fatty acid biosynthetic process. Located in mitochondrion. Implicated in IgA glomerulonephritis. Biomarker of ulcerative colitis. [provided by Alliance of Genome Resources, Apr 2022]
ERI2 (HGNC:30541): (ERI1 exoribonuclease family member 2) Predicted to enable 3'-5'-exoribonuclease activity. Predicted to be involved in exonucleolytic trimming to generate mature 3'-end of 5.8S rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.783G>C (p.R261S) alteration is located in exon 6 (coding exon 5) of the ACSM3 gene. This alteration results from a G to C substitution at nucleotide position 783, causing the arginine (R) at amino acid position 261 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
