Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.2584A>C (p.K862Q) alteration is located in exon 32 (coding exon 31) of the COL28A1 gene. This alteration results from a A to C substitution at nucleotide position 2584, causing the lysine (K) at amino acid position 862 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
