The c.86T>A (p.M29K) alteration is located in exon 2 (coding exon 2) of the TMEM18 gene. This alteration results from a T to A substitution at nucleotide position 86, causing the methionine (M) at amino acid position 29 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
