Genes affected

ADAMTSL4 (HGNC:19706): (ADAMTS like 4) This gene is a member of ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs)-like gene family and encodes a protein with seven thrombospondin type 1 repeats. The thrombospondin type 1 repeat domain is found in many proteins with diverse biological functions including cellular adhesion, angiogenesis, and patterning of the developing nervous system. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Sep 2014]

This sequence change creates a premature translational stop signal (p.Arg276Serfs*21) in the ADAMTSL4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ADAMTSL4 are known to be pathogenic (PMID: 20564469, 28642162). This variant is present in population databases (rs754883702, gnomAD 0.1%), including at least one homozygous and/or hemizygous individual. This premature translational stop signal has been observed in individual(s) with ectopia lentis (PMID: 20564469). ClinVar contains an entry for this variant (Variation ID: 39556). For these reasons, this variant has been classified as Pathogenic. -
