Variant summary

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

The ENST00000390548.6(IGHG1):​c.290A>T​(p.Lys97Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K97R) has been classified as Likely benign.

Genes affected

IGHG1 (HGNC:5525): (immunoglobulin heavy constant gamma 1 (G1m marker)) Predicted to enable antigen binding activity and immunoglobulin receptor binding activity. Predicted to be involved in several processes, including activation of immune response; defense response to other organism; and phagocytosis. Predicted to act upstream of or within several processes, including immunoglobulin mediated immune response; positive regulation of hypersensitivity; and positive regulation of phagocytosis. Located in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]
