Genes affected
COBL (HGNC:22199): (cordon-bleu WH2 repeat protein) This gene encodes a protein that contains WH2 domains (WASP, Wiskott-Aldrich syndrome protein, homology domain-2) that interact with actin. The encoded actin regulator protein is required for growth and assembly of brush border microvilli that play a role in maintaining intestinal homeostasis. A similar protein in mouse functions in midbrain neural tube closure. A pseudogene of this gene is located on chromosome X. [provided by RefSeq, Oct 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2022The c.3550G>A (p.A1184T) alteration is located in exon 12 (coding exon 12) of the COBL gene. This alteration results from a G to A substitution at nucleotide position 3550, causing the alanine (A) at amino acid position 1184 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
