  In this paper we aim to specify some characteristics of the so called family
of $q$-Appell Polynomials by using $q$-Umbral calculus. Next in our study, we
focus on $q$-Genocchi numbers and polynomials as a famous member of this
family. To do this, firstly we show that any arbitrary polynomial can be
written based on a linear combination of $q$-Genocchi polynomials. Finally, we
approach to the point that similar properties can be found for the other
members of the class of $q$-Appell polynomials.
