Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV001089967 SCV001244969 pathogenic Intellectual disability, autosomal recessive 58 2018-09-11 criteria provided, single submitter clinical testing A heterozygous nonsense variant, NM_001242875.1(ELP2):c.1852C>T, has been identified in exon 17 of 23 of the ELP2 gene. The variant is predicted to result in a premature stop codon at position 618 of the protein (NP_001229804.1(ELP2):p.(Gln618*)), likely causing non-sense mediated decay. This variant is predicted to result in loss of protein function either through truncation (loss of >50% of protein) or nonsense -mediated decay, which is a reported mechanism of pathogenicity for this gene. One other frameshift variant has previously been described in this gene (DECIPHER). The variant is present in the gnomAD database at a frequency of 0.001627% (4 het, 0 hom). Analysis of parental samples indicated this variant was maternally inherited. Based on the information available at the time of curation, this variant has been classified as PATHOGENIC.
