The c.410C>G (p.T137S) alteration is located in exon 5 (coding exon 4) of the LRRC27 gene. This alteration results from a C to G substitution at nucleotide position 410, causing the threonine (T) at amino acid position 137 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
