Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.1787C>T (p.A596V) alteration is located in exon 8 (coding exon 8) of the CCDC142 gene. This alteration results from a C to T substitution at nucleotide position 1787, causing the alanine (A) at amino acid position 596 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
