Genes affected
ACSBG2 (HGNC:24174): (acyl-CoA synthetase bubblegum family member 2) Enables acyl-CoA hydrolase activity and arachidonate-CoA ligase activity. Acts upstream of or within fatty acid metabolic process. Located in cytosol and mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
RFX2 (HGNC:9983): (regulatory factor X2) This gene is a member of the regulatory factor X gene family, which encodes transcription factors that contain a highly-conserved winged helix DNA binding domain. The protein encoded by this gene is structurally related to regulatory factors X1, X3, X4, and X5. It is a transcriptional activator that can bind DNA as a monomer or as a heterodimer with other RFX family members. This protein can bind to cis elements in the promoter of the IL-5 receptor alpha gene. Two transcript variants encoding different isoforms have been described for this gene, and both variants utilize alternative polyadenylation sites. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.827T>C (p.I276T) alteration is located in exon 8 (coding exon 7) of the ACSBG2 gene. This alteration results from a T to C substitution at nucleotide position 827, causing the isoleucine (I) at amino acid position 276 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
