Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 15, 2021 | The c.1348C>T (p.R450C) alteration is located in exon 9 (coding exon 9) of the MMP19 gene. This alteration results from a C to T substitution at nucleotide position 1348, causing the arginine (R) at amino acid position 450 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
