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

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BP6: Variant 14-69879262-T-A is Benign according to our data. Variant chr14-69879262-T-A is described in ClinVar as [Benign]. Clinvar id is 1279971.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0149 (2263/151814) while in subpopulation NFE AF= 0.0198 (1345/67892). AF 95% confidence interval is 0.0189. There are 37 homozygotes in gnomad4. There are 1245 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 37 AR gene
