Genes affected

RALGDS (HGNC:9842): (ral guanine nucleotide dissociation stimulator) Guanine nucleotide dissociation stimulators (GDSs, or exchange factors), such as RALGDS, are effectors of Ras-related GTPases (see MIM 190020) that participate in signaling for a variety of cellular processes.[supplied by OMIM, Nov 2010]

RALGDS Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder
