Collection Method: clinical testing

The c.727T>C (p.F243L) alteration is located in exon 7 (coding exon 6) of the TMEM184A gene. This alteration results from a T to C substitution at nucleotide position 727, causing the phenylalanine (F) at amino acid position 243 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
