Genes affected

GADD45A (HGNC:4095): (growth arrest and DNA damage inducible alpha) This gene is a member of a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. The protein encoded by this gene responds to environmental stresses by mediating activation of the p38/JNK pathway via MTK1/MEKK4 kinase. The DNA damage-induced transcription of this gene is mediated by both p53-dependent and -independent mechanisms. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.[provided by RefSeq, Dec 2010]

GADD45A (HGNC:):

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.42).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.116 is higher than 0.05.
