Genes affected
HDC (HGNC:4855): (histidine decarboxylase) This gene encodes a member of the group II decarboxylase family and forms a homodimer that converts L-histidine to histamine in a pyridoxal phosphate dependent manner. Histamine regulates several physiologic processes, including neurotransmission, gastric acid secretion,inflamation, and smooth muscle tone.[provided by RefSeq, Aug 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2024The c.1528A>G (p.S510G) alteration is located in exon 12 (coding exon 12) of the HDC gene. This alteration results from a A to G substitution at nucleotide position 1528, causing the serine (S) at amino acid position 510 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
