Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.463G>A (p.A155T) alteration is located in exon 5 (coding exon 5) of the CNPPD1 gene. This alteration results from a G to A substitution at nucleotide position 463, causing the alanine (A) at amino acid position 155 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
