Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.760A>G (p.T254A) alteration is located in exon 2 (coding exon 2) of the DPCR1 gene. This alteration results from a A to G substitution at nucleotide position 760, causing the threonine (T) at amino acid position 254 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
