Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2024The c.1754T>C (p.M585T) alteration is located in exon 16 (coding exon 14) of the CLGN gene. This alteration results from a T to C substitution at nucleotide position 1754, causing the methionine (M) at amino acid position 585 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
