Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 03, 2023The c.1603G>T (p.D535Y) alteration is located in exon 14 (coding exon 12) of the CLGN gene. This alteration results from a G to T substitution at nucleotide position 1603, causing the aspartic acid (D) at amino acid position 535 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
