Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.550G>A (p.V184M) alteration is located in exon 6 (coding exon 6) of the CNPPD1 gene. This alteration results from a G to A substitution at nucleotide position 550, causing the valine (V) at amino acid position 184 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
