Genes affected

SAMD9 (HGNC:1348): (sterile alpha motif domain containing 9) This gene encodes a sterile alpha motif domain-containing protein. The encoded protein localizes to the cytoplasm and may play a role in regulating cell proliferation and apoptosis. Mutations in this gene are the cause of normophosphatemic familial tumoral calcinosis. Alternate splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq, Jul 2010]

The SAMD9 c.4729T>C variant is predicted to result in the amino acid substitution p.Ser1577Pro. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.020% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-92730682-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 1577 of the SAMD9 protein (p.Ser1577Pro). This variant is present in population databases (rs373623328, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with SAMD9-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
