Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.4459G>A (p.A1487T) alteration is located in exon 56 (coding exon 56) of the COL24A1 gene. This alteration results from a G to A substitution at nucleotide position 4459, causing the alanine (A) at amino acid position 1487 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
