    ### Response:
    The VHL, RET, SDHB, and SDHD genes can be mutated in both syndromic and nonsyndromic forms of paraganglioma and pheochromocytoma. Mutations in at least three additional genes, TMEM127, SDHA, and KIF1B, have been identified in people with the nonsyndromic form of these conditions.
