The c.1309G>A (p.E437K) alteration is located in exon 14 (coding exon 14) of the FRMD5 gene. This alteration results from a G to A substitution at nucleotide position 1309, causing the glutamic acid (E) at amino acid position 437 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
