  We report on results of electrical resistivity and structural investigations
on the cubic modification of FeGe under high pressure. The long-wavelength
helical order ($T_C=280$ K) is suppressed at a critical pressure $p_c\approx
19$ GPa. An anomaly in the resistivity data at $T_X(p)$ and strong deviations
from a Fermi-liquid behavior in a wide pressure range above $p_c$ suggest that
the suppression of $T_C$ disagrees with the standard notion of a quantum
critical phase transition. The metallic ground state persisting at high
pressure can be described by band-structure calculations if structural disorder
due to zero-point motion is included. Discontinuous changes in the pressure
dependence of the shortest Fe-Ge interatomic distance occurring close to the
$T_C(p)$ phase line could be interpreted as a symmetry-conserving transition of
first order.
