The c.268T>C (p.S90P) alteration is located in exon 3 (coding exon 3) of the TMEM134 gene. This alteration results from a T to C substitution at nucleotide position 268, causing the serine (S) at amino acid position 90 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
