Genes affected

DRC12 (HGNC:27446): (dynein regulatory complex subunit 12 homolog) Enables identical protein binding activity. [provided by Alliance of Genome Resources, Apr 2022]

DRC12 links:

NHERF4 (HGNC:19891): (NHERF family PDZ scaffold protein 4) Guanylyl cyclase C (GCC, or GUCY2C; MIM 601330) produces cGMP following the binding of either endogenous ligands or heat-stable enterotoxins secreted by E. coli and other enteric bacteria. Activation of GCC initiates a signaling cascade that leads to phosphorylation of the cystic fibrosis transmembrane conductance regulator (CFTR; MIM 602421), followed by a net efflux of ions and water into the intestinal lumen. IKEPP is a regulatory protein that associates with GCC and regulates the amount of cGMP produced following receptor stimulation (Scott et al., 2002 [PubMed 11950846]).[supplied by OMIM, Mar 2008]

The c.556G>A (p.A186T) alteration is located in exon 7 (coding exon 6) of the CCDC153 gene. This alteration results from a G to A substitution at nucleotide position 556, causing the alanine (A) at amino acid position 186 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
