Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.1024C>T (p.H342Y) 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 1024, causing the histidine (H) at amino acid position 342 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
