Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2024The c.1953C>A (p.D651E) alteration is located in exon 3 (coding exon 3) of the PTCHD4 gene. This alteration results from a C to A substitution at nucleotide position 1953, causing the aspartic acid (D) at amino acid position 651 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
