Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.433C>G (p.L145V) alteration is located in exon 2 (coding exon 1) of the C2CD4A gene. This alteration results from a C to G substitution at nucleotide position 433, causing the leucine (L) at amino acid position 145 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
