Genes affected
RAPGEF3 (HGNC:16629): (Rap guanine nucleotide exchange factor 3) Enables guanyl-nucleotide exchange factor activity and protein domain specific binding activity. Involved in several processes, including positive regulation of protein modification process; regulation of actin cytoskeleton organization; and regulation of syncytium formation by plasma membrane fusion. Located in filopodium; lamellipodium; and microvillus. Colocalizes with cortical actin cytoskeleton and plasma membrane. Biomarker of congestive heart failure.

RPAP3-DT (HGNC:55477): (RPAP3 divergent transcript)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.2548C>T (p.R850W) alteration is located in exon 26 (coding exon 26) of the RAPGEF3 gene. This alteration results from a C to T substitution at nucleotide position 2548, causing the arginine (R) at amino acid position 850 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
