Genes affected

SMOC1 (HGNC:20318): (SPARC related modular calcium binding 1) This gene encodes a multi-domain secreted protein that may have a critical role in ocular and limb development. Mutations in this gene are associated with microphthalmia and limb anomalies. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.82).

BP7

Synonymous conserved (PhyloP=-0.367 with no splicing effect.

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000215 (31/1439020) while in subpopulation AMR AF= 0.000527 (23/43682). AF 95% confidence interval is 0.000359. There are 0 homozygotes in gnomad4_exome. There are 14 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
