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]
LINC02690 (HGNC:54194): (long intergenic non-protein coding RNA 2690)

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000743 (113/152066) while in subpopulation AFR AF = 0.00246 (102/41488). AF 95% confidence interval is 0.00207. There are 0 homozygotes in GnomAd4. There are 46 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
