not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 25, 2024The c.772G>A (p.A258T) alteration is located in exon 7 (coding exon 7) of the PLPP4 gene. This alteration results from a G to A substitution at nucleotide position 772, causing the alanine (A) at amino acid position 258 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
