The c.4651C>T (p.R1551C) alteration is located in exon 22 (coding exon 22) of the TSPOAP1 gene. This alteration results from a C to T substitution at nucleotide position 4651, causing the arginine (R) at amino acid position 1551 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
