SLC5A3

Overview

SLC5A3 (Solute Carrier Family 5 Member 3), also known as SMIT (Sodium/Myo-Inositol Transporter), is a membrane transporter linked to mitochondrial function. It was nominated as a significantly mutated gene in papillary renal cell carcinoma with evidence of tumor-suppressor function.

Alterations observed in the corpus

  • SLC5A3 identified as a significantly mutated gene in papillary renal cell carcinoma (pRCC); three frameshift loss-of-function mutations plus one predicted-damaging point mutation; suggests a tumor-suppressor role linked to mitochondrial alterations PMID:25401301

Cancer types (linked)

  • PRCC — significantly mutated; loss-of-function pattern with three frameshift mutations; functional role linked to mitochondrial biology PMID:25401301

Co-occurrence and mutual exclusivity

Therapeutic relevance

Open questions

  • Oncogenic versus passenger status of SLC5A3 mutations in pRCC lacks functional characterization in cancer PMID:25401301
