Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2022The c.4454A>G (p.N1485S) alteration is located in exon 56 (coding exon 56) of the COL24A1 gene. This alteration results from a A to G substitution at nucleotide position 4454, causing the asparagine (N) at amino acid position 1485 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
