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]

The c.1006G>A (p.A336T) alteration is located in exon 9 (coding exon 8) of the ACSBG2 gene. This alteration results from a G to A substitution at nucleotide position 1006, causing the alanine (A) at amino acid position 336 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
