Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2024The c.679C>T (p.R227W) 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 679, causing the arginine (R) at amino acid position 227 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
