The c.2602C>T (p.R868C) alteration is located in exon 18 (coding exon 18) of the TMEM245 gene. This alteration results from a C to T substitution at nucleotide position 2602, causing the arginine (R) at amino acid position 868 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
