The c.413C>T (p.S138F) alteration is located in exon 5 (coding exon 5) of the TMEM87A gene. This alteration results from a C to T substitution at nucleotide position 413, causing the serine (S) at amino acid position 138 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
