Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.275C>G (p.S92C) alteration is located in exon 2 (coding exon 1) of the ENPP4 gene. This alteration results from a C to G substitution at nucleotide position 275, causing the serine (S) at amino acid position 92 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
