The c.445G>A (p.D149N) alteration is located in exon 4 (coding exon 4) of the LIPK gene. This alteration results from a G to A substitution at nucleotide position 445, causing the aspartic acid (D) at amino acid position 149 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
