The c.463C>T (p.R155C) alteration is located in exon 7 (coding exon 4) of the FAM149A gene. This alteration results from a C to T substitution at nucleotide position 463, causing the arginine (R) at amino acid position 155 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
