Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.4738A>C (p.S1580R) alteration is located in exon 58 (coding exon 58) of the COL24A1 gene. This alteration results from a A to C substitution at nucleotide position 4738, causing the serine (S) at amino acid position 1580 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
