The c.1036G>A (p.E346K) alteration is located in exon 9 (coding exon 7) of the FAM114A1 gene. This alteration results from a G to A substitution at nucleotide position 1036, causing the glutamic acid (E) at amino acid position 346 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
