The c.257G>C (p.S86T) alteration is located in exon 1 (coding exon 1) of the MRFAP1L1 gene. This alteration results from a G to C substitution at nucleotide position 257, causing the serine (S) at amino acid position 86 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
