Variant 9-38067931-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_003028.3(SHB):c.715A>G(p.Lys239Glu) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.0000308 in 1,526,806 control chromosomes in the GnomAD database, with no homozygous occurrence. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K239R) has been classified as Uncertain significance.

Genes affected

SHB (HGNC:10838): (SH2 domain containing adaptor protein B) Enables phosphotyrosine residue binding activity. Predicted to be involved in several processes, including angiogenesis; apoptotic process; and signal transduction. Predicted to act upstream of or within several processes, including hematopoietic stem cell proliferation; negative regulation of oocyte maturation; and positive regulation of immune response. Located in cytoplasmic ribonucleoprotein granule; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.715A>G (p.K239E) alteration is located in exon 1 (coding exon 1) of the SHB gene. This alteration results from a A to G substitution at nucleotide position 715, causing the lysine (K) at amino acid position 239 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
