The c.728C>T (p.A243V) alteration is located in exon 7 (coding exon 6) of the SCAF1 gene. This alteration results from a C to T substitution at nucleotide position 728, causing the alanine (A) at amino acid position 243 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
