Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.1001C>T (p.A334V) alteration is located in exon 10 (coding exon 7) of the CCDC36 gene. This alteration results from a C to T substitution at nucleotide position 1001, causing the alanine (A) at amino acid position 334 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
