Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2022The c.737C>T (p.A246V) alteration is located in exon 8 (coding exon 8) of the CNPPD1 gene. This alteration results from a C to T substitution at nucleotide position 737, causing the alanine (A) at amino acid position 246 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
