We report the magnetic and transport properties of single-crystalline ${\mathrm{Ce}}_4{\mathrm{Ge}}_7$, which crystallizes in a noncentrosymmetric orthorhombic structure (space group $C{222}_1$ ). It undergoes an antiferromagnetic transition at $T_{\mathrm{N}}=7.3\mathrm{K}$. When a magnetic field is applied along the $b$ axis, a metamagnetic transition occurs at 1.3 T (at 2 K) and vanishes above $T_{\mathrm{N}}$. Correspondingly, this transition gives rise to an anomalous Hall effect, which is dominated by the intrinsic Karplus-Luttinger mechanism. Under hydrostatic pressure, $T_{\mathrm{N}}$ of ${\mathrm{Ce}}_4{\mathrm{Ge}}_7$ initially increases slightly and is then gradually suppressed. For pressures above $P_{\mathrm{c}}=10.2\mathrm{GPa}$, no magnetic order is observed. The divergence of the $A$ coefficient, the maximum of the residual resistivity, and the non-Fermi liquid behavior around $P_{\mathrm{c}}$ indicate the possible existence of an antiferromagnetic quantum critical point in ${\mathrm{Ce}}_4{\mathrm{Ge}}_7$.
