Genes affected
RFTN1 (HGNC:30278): (raftlin, lipid raft linker 1) Enables double-stranded RNA binding activity. Involved in B cell receptor signaling pathway; membrane raft assembly; and positive regulation of growth rate. Acts upstream of or within dsRNA transport; response to exogenous dsRNA; and toll-like receptor 3 signaling pathway. Located in endosome; membrane raft; and plasma membrane. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.724G>A (p.G242R) alteration is located in exon 5 (coding exon 4) of the RFTN1 gene. This alteration results from a G to A substitution at nucleotide position 724, causing the glycine (G) at amino acid position 242 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
