The c.2552T>C (p.L851S) alteration is located in exon 12 (coding exon 12) of the FAM184A gene. This alteration results from a T to C substitution at nucleotide position 2552, causing the leucine (L) at amino acid position 851 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
