Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.617C>T (p.T206I) alteration is located in exon 7 (coding exon 7) of the CNPPD1 gene. This alteration results from a C to T substitution at nucleotide position 617, causing the threonine (T) at amino acid position 206 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
