Variant summary: The COL3A1 c.1106G>T (p.Gly369Val) variant involves the alteration of a conserved nucleotide located in the Collagen triple helix repeat(IPR008160) (InterPro) affecting a critical glycine. 5/5 in silico tools predict a damaging outcome for this variant. This variant is absent in 171136 control chromosomes in gnomAD. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as likely pathogenic.
