Feb 13, 2024

The c.442G>A (p.D148N) alteration is located in exon 3 (coding exon 1) of the PHOSPHO1 gene. This alteration results from a G to A substitution at nucleotide position 442, causing the aspartic acid (D) at amino acid position 148 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
