The HSPG2 c.12874G>A; p.Glu4292Lys variant (rs141280063) is reported in the literature in an individual with idiopathic scoliosis (Baschal 2014), though, to our knowledge, it has not been described in association with a congenital skeletal dysplasia. This variant is found in the Finnish European population with an overall allele frequency of 0.98% (243/24858 alleles) in the Genome Aggregation Database. The glutamate at codon 4292 is weakly conserved and computational analyses (SIFT: tolerate, PolyPhen-2: damaging) predict conflicting effects of this variant on protein structure/function. However, given the lack of clinical and functional data, the significance of the p.Glu4292Lys variant is uncertain at this time. References: Baschal EE et al. Exome sequencing identifies a rare HSPG2 variant associated with familial idiopathic scoliosis. G3 (Bethesda). 2014 Dec 12;5(2):167-74 -

Lethal Kniest-like syndrome Benign:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -

HSPG2-related disorder Benign:1
This variant is classified as benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Schwartz-Jampel syndrome Benign:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -
