Genes affected

SH2B1 (HGNC:30417): (SH2B adaptor protein 1) This gene encodes a member of the SH2-domain containing mediators family. The encoded protein mediates activation of various kinases and may function in cytokine and growth factor receptor signaling and cellular transformation. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]

The SH2B1 c.80G>A variant is predicted to result in the amino acid substitution p.Arg27Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.086% of alleles in individuals of South Asian descent in gnomAD, which may be too common to be an unreported cause of disease. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

The c.80G>A (p.R27Q) alteration is located in exon 2 (coding exon 1) of the SH2B1 gene. This alteration results from a G to A substitution at nucleotide position 80, causing the arginine (R) at amino acid position 27 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
