Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.1718G>A (p.S573N) alteration is located in exon 15 (coding exon 13) of the CLGN gene. This alteration results from a G to A substitution at nucleotide position 1718, causing the serine (S) at amino acid position 573 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
