Genes affected

AAMDC (HGNC:30205): (adipogenesis associated Mth938 domain containing) Predicted to be involved in positive regulation of fat cell differentiation. Predicted to act upstream of or within negative regulation of apoptotic process and positive regulation of transcription by RNA polymerase II. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

AAMDC links:

RSF1 (HGNC:18118): (remodeling and spacing factor 1) This gene encodes a nuclear protein that interacts with hepatitis B virus X protein (HBX) and facilitates transcription of hepatitis B virus genes by the HBX transcription activator, suggesting a role for this interaction in the virus life cycle. This protein also interacts with SNF2H protein to form the RSF chromatin-remodeling complex, where the SNF2H subunit functions as the nucleosome-dependent ATPase, and this protein as the histone chaperone.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.53G>C (p.G18A) alteration is located in exon 2 (coding exon 1) of the AAMDC gene. This alteration results from a G to C substitution at nucleotide position 53, causing the glycine (G) at amino acid position 18 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
