Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004789685 SCV005399793 likely pathogenic Abetalipoproteinaemia 2024-10-09 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 abetalipoproteinaemia (MIM#200100). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0115 - Variants in this gene are known to have variable expressivity. Mild cases of of abetalipoproteinaemia have been reported (PMID: 17132287, 16143868). (I) 0211 - Canonical splice site variant without proven consequence on splicing (no functional evidence available). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0508 - In silico predictions for abnormal splicing are conflicting. (I) 0704 - Another canonical splice variant comparable to the one identified in this case has limited previous evidence for pathogenicity. c.61+1G>C has been reported once in a compound heterozygous individual with mild abetalipoproteinaemia (PMID: 16143868). (SP) 0803 - This variant has limited previous evidence of pathogenicity in an unrelated individual. It has been reported once in a compound heterozygous individual affected with mild abetalipoproteinaemia (PMID: 17132287). (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1102 - Strong phenotype match for this individual. (SP) 1205 - This variant has been shown to be maternally inherited (by trio analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
