Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.476C>T (p.T159M) alteration is located in exon 2 (coding exon 2) of the DPCR1 gene. This alteration results from a C to T substitution at nucleotide position 476, causing the threonine (T) at amino acid position 159 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
