Need gauss like PDF with skewness

    need "gauss like" PDF with skewness

    I am looking for a Probability Density Function that has the following properties:
    1. is defined on R like the gaussian
    2. has a non null (and non constant) skewness that is controlled by a parameter
    3. degenerates towards the gaussian

    At the moment I am using a beta function but it does not meet requirements (1) and (3).

    I checked the Pearson system but only the generating differential equation degenerates to that of the gaussian, not its solution... see what I mean?

    I say, good luck to you. I don't think any of the commonly used distributions satisfy all of the 3 properties.
