The c.107T>C (p.V36A) alteration is located in exon 1 (coding exon 1) of the TMEM260 gene. This alteration results from a T to C substitution at nucleotide position 107, causing the valine (V) at amino acid position 36 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
