Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2022The c.449C>T (p.A150V) alteration is located in exon 5 (coding exon 5) of the CNPPD1 gene. This alteration results from a C to T substitution at nucleotide position 449, causing the alanine (A) at amino acid position 150 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
