The c.970G>A (p.A324T) alteration is located in exon 6 (coding exon 5) of the ABHD17A gene. This alteration results from a G to A substitution at nucleotide position 970, causing the alanine (A) at amino acid position 324 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
