Department of Pediatrics, National Cheng-Kung University Hospital RCV003338924 SCV004046846 likely pathogenic Orofaciodigital syndrome type 14 no assertion criteria provided clinical testing The Y907C allele in C2CD3 is a novel missense variant predicted to be pathogenic by multiple in silico predictive software. Identified through Whole Exome Sequencing (WES), it was found in a compound heterozygous state in a male patient whose clinical presentation aligns with the diagnosis of Oral-Facial-Digital syndrome (OFDS) 14. Clinical manifestations include dysmorphism, microcephaly, trigonocephaly, ambiguous genitalia, and intellectual disability. The variant is located at the C2 domain of the C2CD3 protein, known to function in protein-protein interactions. Additionally, it affects an evolutionarily conserved amino acid residue of the C2CD3 protein. In summary, the variant meets two moderate (PM2) and two supporting (PP3 and PP4) ACMG criteria during variant interpretation; therefore, it is classified as likely pathogenic.
