Genes affected

NEUROG3 (HGNC:13806): (neurogenin 3) The protein encoded by this gene is a basic helix-loop-helix (bHLH) transcription factor involved in neurogenesis. The encoded protein likely acts as a heterodimer with another bHLH protein. Defects in this gene are a cause of congenital malabsorptive diarrhea 4 (DIAR4).[provided by RefSeq, May 2010]

The NEUROG3 c.319C>A variant is predicted to result in the amino acid substitution p.Arg107Ser. This variant was reported in the homozygous state in multiple individuals with congenital malabsorptive diarrhea (Wang et al. 2006. PubMed ID: 16855267; Rubio-Cabezas et al. 2016. PubMed ID: 27533310; Germán-Díaz et al. 2017. PubMed ID: 28724572). This variant is reported in 0.011% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/10-71332481-G-T). This variant is interpreted as likely pathogenic. -
