The c.385G>A (p.A129T) alteration is located in exon 7 (coding exon 5) of the TMEM63C gene. This alteration results from a G to A substitution at nucleotide position 385, causing the alanine (A) at amino acid position 129 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
