Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1234G>T (p.G412C) alteration is located in exon 12 (coding exon 10) of the CLGN gene. This alteration results from a G to T substitution at nucleotide position 1234, causing the glycine (G) at amino acid position 412 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
