The c.679T>C (p.F227L) alteration is located in exon 5 (coding exon 5) of the TMEM30A gene. This alteration results from a T to C substitution at nucleotide position 679, causing the phenylalanine (F) at amino acid position 227 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
