NCI Definition: Abnormal malignant growth of cells in the urethra (lower urinary tract). [1]

Malignant urethral neoplasms most frequently harbor alterations in TP53, FGFR3, PIK3CA, CDKN2A, and KDM6A [2].

Most Commonly Altered Genes in Malignant Urethral Neoplasm

TP53 Mutation, TP53 Missense, TP53 c.217-c.1178 Missense, FGFR3 Mutation, and TP53 Exon 8 Mutation are the most common alterations in malignant urethral neoplasm [2].
