The c.974A>T (p.D325V) alteration is located in exon 7 (coding exon 7) of the ABHD4 gene. This alteration results from a A to T substitution at nucleotide position 974, causing the aspartic acid (D) at amino acid position 325 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
