Labcorp Genetics (formerly Invitae), Labcorp	RCV003061260	SCV003460851	uncertain significance	Immunodeficiency 67	2022-07-01	criteria provided, single submitter	clinical testing	In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt IRAK4 protein function. This variant has not been reported in the literature in individuals affected with IRAK4-related conditions. This variant is present in population databases (rs762667477, gnomAD 0.02%). This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 254 of the IRAK4 protein (p.Asp254Tyr).
Ambry Genetics	RCV004071691	SCV004890826	uncertain significance	Inborn genetic diseases	2024-01-16	criteria provided, single submitter	clinical testing	The c.760G>T (p.D254Y) alteration is located in exon 7 (coding exon 6) of the IRAK4 gene. This alteration results from a G to T substitution at nucleotide position 760, causing the aspartic acid (D) at amino acid position 254 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
