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]

Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Jul 06, 2021	Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; This variant is associated with the following publications: (PMID: 25525159, 27535533, 20564469, 31589614) -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 14, 2023	This sequence change creates a premature translational stop signal (p.Arg670*) 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 (rs368482584, gnomAD 0.007%). 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: 39557). For these reasons, this variant has been classified as Pathogenic. -

ADAMTSL4 NM_019032.5 exon 12 p.Arg670* (c.2008C>T): This variant has been reported in the literature in the homozygous state in one individual with isolated ectopia lentis, segregating with disease in one affected family members (Aragon-Martin 2010 PMID:20564469). This variant is also present in 0.006% (1/15690) of African alleles in the Genome Aggregation Database https://gnomad.broadinstitute.org/variant/1-150529772-C-T). Please note, disease causing variants may be present in control databases at low frequencies, reflective of the general population, carrier status, and/or variable expressivity. This variant is present in ClinVar (Variation ID:39557). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant is predicted to cause a stopgain at this codon, resulting in protein truncation or loss of allelic expression through nonsense-mediated mRNA decay. Loss of function variants have been reported in association with disease for this gene (Aragon-Martin 2010 PMID:20564469, Chandra 2012 PMID:22736615, Neuhann 2015 PMID:25975359). In summary, data on this variant is highly suspicious for disease, but requires further evidence for pathogenicity. Therefore, this variant is classified as likely pathogenic. -
