Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.581G>A (p.S194N) 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 581, causing the serine (S) at amino acid position 194 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
