Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 29, 2024The c.1621C>T (p.L541F) alteration is located in exon 3 (coding exon 3) of the PTCHD4 gene. This alteration results from a C to T substitution at nucleotide position 1621, causing the leucine (L) at amino acid position 541 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
