The c.790G>T (p.V264L) alteration is located in exon 1 (coding exon 1) of the ACTL8 gene. This alteration results from a G to T substitution at nucleotide position 790, causing the valine (V) at amino acid position 264 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
