Genes affected
FYB1 (HGNC:4036): (FYN binding protein 1) The protein encoded by this gene is an adapter for the FYN protein and LCP2 signaling cascades in T-cells. The encoded protein is involved in platelet activation and controls the expression of interleukin-2. Three transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2023The c.2136G>T (p.M712I) alteration is located in exon 1 (coding exon 1) of the FYB gene. This alteration results from a G to T substitution at nucleotide position 2136, causing the methionine (M) at amino acid position 712 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
