Genes affected

COL14A1 (HGNC:2191): (collagen type XIV alpha 1 chain) This gene encodes the alpha chain of type XIV collagen, a member of the FACIT (fibril-associated collagens with interrupted triple helices) collagen family. Type XIV collagen interacts with the fibril surface and is involved in the regulation of fibrillogenesis. [provided by RefSeq, Jan 2013]

The c.350T>C (p.I117T) alteration is located in exon 5 (coding exon 4) of the COL14A1 gene. This alteration results from a T to C substitution at nucleotide position 350, causing the isoleucine (I) at amino acid position 117 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
