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. [provided by RefSeq, Mar 2011]

SMOC1 Gene-Disease associations (from GenCC):

• microphthalmia with limb anomalies

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), PanelApp Australia, Orphanet, G2P

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 14-70011466-C-A is Benign according to our data. Variant chr14-70011466-C-A is described in ClinVar as Benign. ClinVar VariationId is 257190.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.389 is higher than 0.05.
