The c.160T>C (p.F54L) alteration is located in exon 2 (coding exon 2) of the TMEM205 gene. This alteration results from a T to C substitution at nucleotide position 160, causing the phenylalanine (F) at amino acid position 54 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
