The c.1960A>G (p.K654E) alteration is located in exon 14 (coding exon 13) of the TMEM232 gene. This alteration results from a A to G substitution at nucleotide position 1960, causing the lysine (K) at amino acid position 654 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
