Genes affected

NAE1 (HGNC:621): (NEDD8 activating enzyme E1 subunit 1) The protein encoded by this gene binds to the beta-amyloid precursor protein. Beta-amyloid precursor protein is a cell surface protein with signal-transducing properties, and it is thought to play a role in the pathogenesis of Alzheimer's disease. In addition, the encoded protein can form a heterodimer with UBE1C and bind and activate NEDD8, a ubiquitin-like protein. This protein is required for cell cycle progression through the S/M checkpoint. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM1: In a site Interaction with UBA3 (size 0) in uniprot entity ULA1_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.771

The c.632A>G (p.H211R) alteration is located in exon 9 (coding exon 9) of the NAE1 gene. This alteration results from a A to G substitution at nucleotide position 632, causing the histidine (H) at amino acid position 211 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
