Invitae RCV000816096 SCV000956586 pathogenic Holoprosencephaly 5 2019-08-15 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the C-terminus of the ZIC2 protein. Other variant(s) that disrupt this region (p.Lys410_His411del) have been observed in individuals with ZIC2-related conditions (Invitae) and determined to be likely pathogenic. This suggests that this may be a clinically significant region of the protein. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the affected amino acid(s) is currently unknown. This variant has been observed in individual(s) with holoprosencephaly (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (ExAC no frequency). This sequence change results in a premature translational stop signal in the ZIC2 gene (p.Ser406Alafs*7). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 127 amino acids of the ZIC2 protein.
