The c.193C>G (p.L65V) alteration is located in exon 1 (coding exon 1) of the TMEM64 gene. This alteration results from a C to G substitution at nucleotide position 193, causing the leucine (L) at amino acid position 65 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
