The c.448T>G (p.L150V) alteration is located in exon 2 (coding exon 1) of the TMEM239 gene. This alteration results from a T to G substitution at nucleotide position 448, causing the leucine (L) at amino acid position 150 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
