Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.535C>T (p.R179W) alteration is located in exon 6 (coding exon 6) of the CNPPD1 gene. This alteration results from a C to T substitution at nucleotide position 535, causing the arginine (R) at amino acid position 179 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
