The c.272A>C (p.Q91P) alteration is located in exon 3 (coding exon 3) of the TMEM134 gene. This alteration results from a A to C substitution at nucleotide position 272, causing the glutamine (Q) at amino acid position 91 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
