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.946G>A (p.A316T) alteration is located in exon 6 (coding exon 5) of the RFTN1 gene. This alteration results from a G to A substitution at nucleotide position 946, causing the alanine (A) at amino acid position 316 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
