The c.155G>A (p.R52K) alteration is located in exon 2 (coding exon 1) of the MFAP3L gene. This alteration results from a G to A substitution at nucleotide position 155, causing the arginine (R) at amino acid position 52 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
