The c.466A>G (p.K156E) alteration is located in exon 8 (coding exon 7) of the TMEM40 gene. This alteration results from a A to G substitution at nucleotide position 466, causing the lysine (K) at amino acid position 156 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
