Genes affected

GATA6 (HGNC:4174): (GATA binding protein 6) This gene is a member of a small family of zinc finger transcription factors that play an important role in the regulation of cellular differentiation and organogenesis during vertebrate development. This gene is expressed during early embryogenesis and localizes to endo- and mesodermally derived cells during later embryogenesis and thereby plays an important role in gut, lung, and heart development. Mutations in this gene are associated with several congenital defects. [provided by RefSeq, Mar 2012]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PM1

In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_005257.6

BP4

Computational evidence support a benign effect (MetaRNN=0.15460134).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000814 (124/152286) while in subpopulation AFR AF = 0.00294 (122/41554). AF 95% confidence interval is 0.00251. There are 0 homozygotes in GnomAd4. There are 70 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method:research

Potent mutations in GATA6 gene are associated with neonatal diabetes, decreased insulin production due to pancreatic aplasia or hypoplasia. Also associated with isolated cardiac abnormalities in children, like atrial septal defects.However no sufficient evidence is found to ascertain the role of this particular variant rs151176879 yet. -
