Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.569C>A (p.A190E) alteration is located in exon 2 (coding exon 1) of the ENPP4 gene. This alteration results from a C to A substitution at nucleotide position 569, causing the alanine (A) at amino acid position 190 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
