Genetic Variant NM_024684.4:c.181G>A (chr11-77869770-G-A) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_024684.4(AAMDC):c.181G>A(p.Gly61Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,710 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G61R) has been classified as Uncertain significance.

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.

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.
