The c.1238C>T (p.T413M) alteration is located in exon 1 (coding exon 1) of the LRFN1 gene. This alteration results from a C to T substitution at nucleotide position 1238, causing the threonine (T) at amino acid position 413 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
