The c.952T>G (p.L318V) alteration is located in exon 10 (coding exon 10) of the TMEM161B gene. This alteration results from a T to G substitution at nucleotide position 952, causing the leucine (L) at amino acid position 318 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
