Description

The p.P475T variant (also known as c.1423C>A), located in coding exon 21 of the COL1A1 gene, results from a C to A substitution at nucleotide position 1423. The proline at codon 475 is replaced by threonine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction by BayesDel for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
