The c.1357A>G (p.T453A) alteration is located in exon 18 (coding exon 18) of the FCHO2 gene. This alteration results from a A to G substitution at nucleotide position 1357, causing the threonine (T) at amino acid position 453 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
