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]

The c.1524G>A (p.M508I) alteration is located in exon 10 (coding exon 9) of the RFTN1 gene. This alteration results from a G to A substitution at nucleotide position 1524, causing the methionine (M) at amino acid position 508 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
