In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 33)
• Consequence: RALGPS2 NM_152663.5 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.439

Genes affected

RALGPS2 (HGNC:30279): (Ral GEF with PH domain and SH3 binding motif 2) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of Ral protein signal transduction; regulation of catalytic activity; and small GTPase mediated signal transduction. Predicted to be located in cytoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification
