Genes affected
SASH1 (HGNC:19182): (SAM and SH3 domain containing 1) This gene encodes a scaffold protein involved in the TLR4 signaling pathway that may stimulate cytokine production and endothelial cell migration in response to invading pathogens. The encoded protein has also been described as a potential tumor suppressor that may negatively regulate proliferation, apoptosis, and invasion of cancer cells, and reduced expression of this gene has been observed in multiple human cancers. Mutations in this gene may be associated with abnormal skin pigmentation in human patients. [provided by RefSeq, Oct 2016]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2023The c.160G>A (p.G54S) alteration is located in exon 2 (coding exon 2) of the SASH1 gene. This alteration results from a G to A substitution at nucleotide position 160, causing the glycine (G) at amino acid position 54 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
