4930524O08Rik (A19) is a transcript located 40 kb upstream of the paternally expressed gene Rasgrf1
and 10 kb upstream of the Rasgrf1 associated repeat sequence and differentially methylated region.
A19 contains six exons and encodes a putative protein of 90 amino acids, although a weak putative
translation start sequence may suggest the transcript is non-coding. A19 is paternally expressed in
adult brain tissue, but biallelically expressed in adult testis (de
la Puente A, et al. 2002).
