The NM_000583.4(GC):c.59-3707G>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.0876 (AC=13,310) in the gnomAD database across 151,994 control chromosomes, including 835 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.225. 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]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Benign. The variant received -12 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	BP4Computational evidence suggests no impact		Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
	BA1Stand-alone benign allele frequency (>5%)		GnomAD effective popmax AF >5% — BA1 stand-alone benign; GnomAD reliable popmax AF = 0.2253 — exceeds 5%% threshold (BA1 applied)
