The c.767T>C (p.M256T) alteration is located in exon 7 (coding exon 6) of the LRRC23 gene. This alteration results from a T to C substitution at nucleotide position 767, causing the methionine (M) at amino acid position 256 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
