The c.484G>A (p.V162M) alteration is located in exon 6 (coding exon 6) of the SCAF8 gene. This alteration results from a G to A substitution at nucleotide position 484, causing the valine (V) at amino acid position 162 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
