The c.252G>C (p.E84D) alteration is located in exon 2 (coding exon 2) of the FAM229A gene. This alteration results from a G to C substitution at nucleotide position 252, causing the glutamic acid (E) at amino acid position 84 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
