Genes affected

SLC35C1 (HGNC:20197): (solute carrier family 35 member C1) This gene encodes a GDP-fucose transporter that is found in the Golgi apparatus. Mutations in this gene result in congenital disorder of glycosylation type IIc. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2009]

Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The SLC35C1 p.Val187Ile variant was not identified in the literature nor was it identified in Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs146971634) and ClinVar (classified as likely benign). The variant was also identified in control databases in 107 of 280140 chromosomes (1 homozygous) at a frequency of 0.000382 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 94 of 24732 chromosomes (freq: 0.003801), Other in 3 of 7176 chromosomes (freq: 0.000418), Latino in 7 of 35384 chromosomes (freq: 0.000198), South Asian in 1 of 30614 chromosomes (freq: 0.000033) and European (non-Finnish) in 2 of 128374 chromosomes (freq: 0.000016), while the variant was not observed in the Ashkenazi Jewish, East Asian, and European (Finnish) populations. The p.Val187 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -

The c.598G>A (p.V200I) alteration is located in exon 2 (coding exon 2) of the SLC35C1 gene. This alteration results from a G to A substitution at nucleotide position 598, causing the valine (V) at amino acid position 200 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
