Genes affected

CYBA (HGNC:2577): (cytochrome b-245 alpha chain) Cytochrome b is comprised of a light chain (alpha) and a heavy chain (beta). This gene encodes the light, alpha subunit which has been proposed as a primary component of the microbicidal oxidase system of phagocytes. Mutations in this gene are associated with autosomal recessive chronic granulomatous disease (CGD), that is characterized by the failure of activated phagocytes to generate superoxide, which is important for the microbicidal activity of these cells.

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Dec 16, 2021	Variant summary: CYBA c.214T>C (p.Tyr72His) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.7 in 250626 control chromosomes, suggesting that it is the major allele and therefore benign. The observed variant frequency is approximately 1139 fold of the estimated maximal expected allele frequency for a pathogenic variant in CYBA causing Chronic Granulomatous Disease phenotype (0.00061), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.214T>C in individuals affected with Chronic Granulomatous Disease and no experimental evidence demonstrating its impact on protein function have been reported. Five ClinVar submitters have assessed the clinical significance of this variant after 2014: four have classified the variant as benign and one as likely pathogenic. Based on the evidence outlined above, the variant was classified as benign. -
