Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2021The c.302A>T (p.H101L) alteration is located in exon 2 (coding exon 1) of the ENPP4 gene. This alteration results from a A to T substitution at nucleotide position 302, causing the histidine (H) at amino acid position 101 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
