Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.940G>A (p.E314K) alteration is located in exon 2 (coding exon 2) of the DPCR1 gene. This alteration results from a G to A substitution at nucleotide position 940, causing the glutamic acid (E) at amino acid position 314 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
