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 GeneticsDec 26, 2023The c.779G>C (p.G260A) alteration is located in exon 5 (coding exon 4) of the ACSM3 gene. This alteration results from a G to C substitution at nucleotide position 779, causing the glycine (G) at amino acid position 260 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
