Genes affected

NPEPL1 (HGNC:16244): (aminopeptidase like 1) Predicted to enable manganese ion binding activity and metalloaminopeptidase activity. Predicted to be involved in proteolysis. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

STX16-NPEPL1 (HGNC:41993): (STX16-NPEPL1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring syntaxin 16 (STX16) and aminopeptidase-like 1 (NPEPL1) genes on chromosome 20. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Mar 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
