The c.137C>T (p.T46I) alteration is located in exon 3 (coding exon 2) of the GPCPD1 gene. This alteration results from a C to T substitution at nucleotide position 137, causing the threonine (T) at amino acid position 46 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
