The c.555C>A (p.F185L) alteration is located in exon 7 (coding exon 7) of the TMEM134 gene. This alteration results from a C to A substitution at nucleotide position 555, causing the phenylalanine (F) at amino acid position 185 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
