Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2022The c.92C>T (p.T31I) 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 92, causing the threonine (T) at amino acid position 31 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
