The c.545C>T (p.S182F) alteration is located in exon 3 (coding exon 1) of the LRRC61 gene. This alteration results from a C to T substitution at nucleotide position 545, causing the serine (S) at amino acid position 182 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
