not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.633T>A (p.D211E) alteration is located in exon 2 (coding exon 1) of the ENPP4 gene. This alteration results from a T to A substitution at nucleotide position 633, causing the aspartic acid (D) at amino acid position 211 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
