The c.1228C>T (p.R410W) alteration is located in exon 13 (coding exon 10) of the PIP5K1B gene. This alteration results from a C to T substitution at nucleotide position 1228, causing the arginine (R) at amino acid position 410 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
