Genes affected
GPR21 (HGNC:4476): (G protein-coupled receptor 21) This gene encodes a member of the G-protein-coupled receptor 1 family. G-protein coupled receptors are membrane proteins which activate signaling cascades as a response to extracellular stress. The encoded protein activates a Gq signal transduction pathway which mobilizes calcium. [provided by RefSeq, Nov 2012]
RABGAP1 (HGNC:17155): (RAB GTPase activating protein 1) Enables GTPase activator activity and small GTPase binding activity. Involved in regulation of GTPase activity. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.1000G>A (p.D334N) alteration is located in exon 1 (coding exon 1) of the GPR21 gene. This alteration results from a G to A substitution at nucleotide position 1000, causing the aspartic acid (D) at amino acid position 334 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
