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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.18326354).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000046 (7/152190) while in subpopulation SAS AF = 0.00104 (5/4828). AF 95% confidence interval is 0.000408. There are 0 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
