The NM_004415.4(DSP):c.5441G>A (p.Ser1814Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene DSP is a tumor suppressor gene (CancerMine: 3 TSG citations). The variant allele was found at a cumulative frequency of 0.00000479 (AC=7) in the gnomAD database across 1,461,372 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.00000262. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.S1814R: Uncertain_significance (ClinVar VariationId 1392061, 1 star); p.S1814= (synonymous): Likely_benign (ClinVar VariationId 2943214, 1 star)

Genes affected

DSP (HGNC:3052): (desmoplakin) This gene encodes a protein that anchors intermediate filaments to desmosomal plaques and forms an obligate component of functional desmosomes. Mutations in this gene are the cause of several cardiomyopathies and keratodermas, including skin fragility-woolly hair syndrome. Alternative splicing results in multiple transcript variants.

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 0 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 = 0.000003 — very rare (O3 supporting [+1])
	B3Computational evidence does not support deleterious effect		Computational evidence does not support a deleterious effect; Missense variant — primary computational scorer does not support an oncogenic/deleterious effect; supports B3
