Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.1252G>A (p.G418R) alteration is located in exon 3 (coding exon 3) of the PTCHD3 gene. This alteration results from a G to A substitution at nucleotide position 1252, causing the glycine (G) at amino acid position 418 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
