The c.217C>A (p.P73T) alteration is located in exon 4 (coding exon 2) of the TMEM108 gene. This alteration results from a C to A substitution at nucleotide position 217, causing the proline (P) at amino acid position 73 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
