Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2022The c.1138G>C (p.A380P) alteration is located in exon 8 (coding exon 8) of the ENPP6 gene. This alteration results from a G to C substitution at nucleotide position 1138, causing the alanine (A) at amino acid position 380 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
