Genes affected
SMAD5 (HGNC:6771): (SMAD family member 5) The protein encoded by this gene is involved in the transforming growth factor beta signaling pathway that results in an inhibition of the proliferation of hematopoietic progenitor cells. The encoded protein is activated by bone morphogenetic proteins type 1 receptor kinase, and may be involved in cancer. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.50G>A (p.R17Q) alteration is located in exon 4 (coding exon 1) of the SMAD5 gene. This alteration results from a G to A substitution at nucleotide position 50, causing the arginine (R) at amino acid position 17 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
