Genes affected

ARPP21 (HGNC:16968): (cAMP regulated phosphoprotein 21) This gene encodes a cAMP-regulated phosphoprotein. The encoded protein is enriched in the caudate nucleus and cerebellar cortex. A similar protein in mouse may be involved in regulating the effects of dopamine in the basal ganglia. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]

Ambry Genetics

Aug 08, 2023

The c.1250G>A (p.G417D) alteration is located in exon 15 (coding exon 13) of the ARPP21 gene. This alteration results from a G to A substitution at nucleotide position 1250, causing the glycine (G) at amino acid position 417 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
