The c.2053G>C (p.E685Q) alteration is located in exon 5 (coding exon 5) of the FAAP100 gene. This alteration results from a G to C substitution at nucleotide position 2053, causing the glutamic acid (E) at amino acid position 685 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
