The variant received 1 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_ModerateB3_Supporting

The NM_001257.5(CDH13):c.109C>T (p.His37Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene CDH13 is a tumor suppressor gene (CancerMine: 12 TSG, 5 oncogene citations). The gene CDH13 is a known oncogene (CancerMine: 12 TSG, 5 oncogene citations). The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.H37N: Uncertain_significance (ClinVar VariationId 2457217, 1 star); p.H37R: Uncertain_significance (ClinVar VariationId 4223670, 1 star)

Genes affected

CDH13 (HGNC:1753): (cadherin 13) This gene encodes a member of the cadherin superfamily. The encoded protein is localized to the surface of the cell membrane and is anchored by a GPI moiety, rather than by a transmembrane domain. The protein lacks the cytoplasmic domain characteristic of other cadherins, and so is not thought to be a cell-cell adhesion glycoprotein. This protein acts as a negative regulator of axon growth during neural differentiation. It also protects vascular endothelial cells from apoptosis due to oxidative stress, and is associated with resistance to atherosclerosis. The gene is hypermethylated in many types of cancer. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2011]

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 1 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Absent or extremely rare in gnomAD (AC ≤ 2) — O3 moderate; GnomAD: AF = absent, AC = 0 — absent/extremely rare (O3 moderate [+2])
	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
