Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.1205G>A (p.R402H) alteration is located in exon 8 (coding exon 8) of the CNPPD1 gene. This alteration results from a G to A substitution at nucleotide position 1205, causing the arginine (R) at amino acid position 402 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
