Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.1766G>A (p.R589Q) alteration is located in exon 3 (coding exon 3) of the PTCHD4 gene. This alteration results from a G to A substitution at nucleotide position 1766, causing the arginine (R) at amino acid position 589 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
