Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2024The c.134A>G (p.E45G) alteration is located in exon 2 (coding exon 1) of the ENPP4 gene. This alteration results from a A to G substitution at nucleotide position 134, causing the glutamic acid (E) at amino acid position 45 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
