Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 02, 2023The c.1823G>A (p.R608Q) alteration is located in exon 16 (coding exon 14) of the CLGN gene. This alteration results from a G to A substitution at nucleotide position 1823, causing the arginine (R) at amino acid position 608 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
