The NM_001144967.3(NEDD4L):c.285C>T (p.Asp95Asp) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The gene NEDD4L is a tumor suppressor gene (CancerMine: 18 TSG, 1 oncogene citations). The gene NEDD4L is a known oncogene (CancerMine: 18 TSG, 1 oncogene citations). The variant allele was found at a cumulative frequency of 0.0000339 (AC=54) in the gnomAD database across 1,591,712 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000887. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★★). The variant has been observed in cBioPortal in 2 samples across 2 studies and 2 cancer types; somatic enrichment level: SUPPORTING_LOW (Observed in a small number of cBioPortal cases.).

Genes affected

NEDD4L (HGNC:7728): (NEDD4 like E3 ubiquitin protein ligase) This gene encodes a member of the Nedd4 family of HECT domain E3 ubiquitin ligases. HECT domain E3 ubiquitin ligases transfer ubiquitin from E2 ubiquitin-conjugating enzymes to protein substrates, thus targeting specific proteins for lysosomal degradation. The encoded protein mediates the ubiquitination of multiple target substrates and plays a critical role in epithelial sodium transport by regulating the cell surface expression of the epithelial sodium channel, ENaC. Single nucleotide polymorphisms in this gene may be associated with essential hypertension. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -3 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Very rare in gnomAD (popmax AF <0.01%) — O3 supporting; GnomAD effective popmax AF = 0.000089 — very rare (O3 supporting [+1])
	B4Synonymous/intronic, no splicing impact		Synonymous/intronic variant with confirmed no splicing impact (B4 strong); Synonymous variant — splicing algorithms confirm no impact on splicing (B4 strong [-4])
