The c.1900G>A (p.E634K) alteration is located in exon 5 (coding exon 5) of the FAAP100 gene. This alteration results from a G to A substitution at nucleotide position 1900, causing the glutamic acid (E) at amino acid position 634 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
