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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.280C>A (p.L94I) alteration is located in exon 6 (coding exon 4) of the ARPP21 gene. This alteration results from a C to A substitution at nucleotide position 280, causing the leucine (L) at amino acid position 94 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
