The c.208C>T (p.L70F) alteration is located in exon 2 (coding exon 2) of the GLT1D1 gene. This alteration results from a C to T substitution at nucleotide position 208, causing the leucine (L) at amino acid position 70 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
