The c.304G>C (p.V102L) alteration is located in exon 2 (coding exon 2) of the TMEM156 gene. This alteration results from a G to C substitution at nucleotide position 304, causing the valine (V) at amino acid position 102 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
