If 'variable is abcdSTATUS and should be empty' what value are you trying 
to get?

In your first try '${${myVar}STATUS}}' you have 1 too many closing brace. 
In your second try '${{myvar}STATUS}' you're missing a 'dollar.'

Is this what you are trying to do?

         exten = *,n,    set(ARG1=abcd)
         exten = *,n,    set(__myVar=${ARG1})
         exten = *,n,    set(__${myVar}STATUS=status)
         exten = *,n,    verbose(myVar = ${myVar})
         exten = *,n,    verbose(dollar{myVar}STATUS = ${${myVar}STATUS})
         exten = *,n,    hangup()
