The c.144C>G (p.D48E) alteration is located in exon 2 (coding exon 2) of the DAGLB gene. This alteration results from a C to G substitution at nucleotide position 144, causing the aspartic acid (D) at amino acid position 48 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
