The c.1660G>A (p.E554K) alteration is located in exon 11 (coding exon 9) of the HECW1 gene. This alteration results from a G to A substitution at nucleotide position 1660, causing the glutamic acid (E) at amino acid position 554 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
