The c.274G>A (p.A92T) alteration is located in exon 4 (coding exon 4) of the CTDSPL gene. This alteration results from a G to A substitution at nucleotide position 274, causing the alanine (A) at amino acid position 92 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
