Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004595302 SCV005086458 likely pathogenic Microcephaly 2, primary, autosomal recessive, with or without cortical malformations 2023-07-17 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with microcephaly 2, primary, autosomal recessive, with or without cortical malformations (MIM#604317). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0208 - Variant is predicted to result in an elongated protein. (SP) 0252 - This variant is homozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0601 - Variant is located in the well-established functional C-terminal region. This variant alters the sequence within the third alpha helix of the C-terminal domain, which has been functionally proven to affect protein dimerization (PMID: 23341463). (SP) 0705 - No comparable elongation variants have previous evidence for pathogenicity. However, another elongation variant beginning upstream of this variant has been classified as likely pathogenic. This variant was observed in an apparently homozygous individual with microcephaly, schizencephaly, polymicrogyria, quadriparesis, global developmental delay, and epilepsy (ClinVar, personal communication). (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1209 - This variant has been shown to be both maternally and paternally inherited (biallelic, by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
