Submissions by phenotype
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 05, 2022 | The c.2039A>G (p.N680S) alteration is located in exon 14 (coding exon 14) of the LAMA2 gene. This alteration results from a A to G substitution at nucleotide position 2039, causing the asparagine (N) at amino acid position 680 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
