The variant received -4 classification points (ACMG Germline Pathogenicity v2019). BP4_Strong

The NM_000583.4(GC):c.59-3707G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.0015 (AC=228) in the gnomAD database across 152,024 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.00966. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

GC (HGNC:4187): (GC vitamin D binding protein) The protein encoded by this gene belongs to the albumin gene family. It is a multifunctional protein found in plasma, ascitic fluid, cerebrospinal fluid and on the surface of many cell types. It binds to vitamin D and its plasma metabolites and transports them to target tissues. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Feb 2011]
