not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.956C>A (p.S319Y) alteration is located in exon 2 (coding exon 2) of the DPCR1 gene. This alteration results from a C to A substitution at nucleotide position 956, causing the serine (S) at amino acid position 319 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
