Comment on variant

NCBI staff reviewed the coordinates of this duplication based on the sequence in Figure 5 of the paper by Pettersson et al., 2018 (PubMed 30080953). These positions are consistent with a duplication of 10.4 KB involving exons 2-5.

(2018) identified heterozygosity for a de novo 10.4-kb intragenic tandem duplication (chr2.20,198,536-20,208,996dup, GRCh37) of exons 2 to 5 in the MATN3 gene. The duplication was predicted to cause premature termination of the MATN3 protein, resulting in complete loss of the last 2 domains of the protein. No patient fibroblasts were available for study.
