The c.757G>A (p.A253T) alteration is located in exon 7 (coding exon 6) of the DAGLA gene. This alteration results from a G to A substitution at nucleotide position 757, causing the alanine (A) at amino acid position 253 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
