The variant received 2 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_Moderate

The NM_030777.4(SLC2A10):c.510G>A (p.Trp170*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant is predicted to lead to nonsense-mediated mRNA decay (NMD). The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely damaging/oncogenic. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Pathogenic/Likely Pathogenic (★).

Genes affected

SLC2A10 (HGNC:13444): (solute carrier family 2 member 10) This gene encodes a member of the class III facilitative glucose transporter family. The encoded protein plays a role in regulation of glucose homeostasis. Mutations in this gene have been associated with arterial tortuosity syndrome.[provided by RefSeq, Dec 2009]

SLC2A10 Gene-Disease associations (from GenCC):

• arterial tortuosity syndrome
