The c.688G>C (p.V230L) alteration is located in exon 5 (coding exon 4) of the TMEM45B gene. This alteration results from a G to C substitution at nucleotide position 688, causing the valine (V) at amino acid position 230 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
