The c.1634C>A (p.T545K) alteration is located in exon 14 (coding exon 14) of the DAGLB gene. This alteration results from a C to A substitution at nucleotide position 1634, causing the threonine (T) at amino acid position 545 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
