Genes affected
HECA (HGNC:21041): (hdc homolog, cell cycle regulator) This gene encodes the homolog of the Drosophila headcase protein, a highly basic, cytoplasmic protein that regulates the re-entry of imaginal cells into the mitotic cycle during adult morphogenesis. In Drosophila, the encoded protein also inhibits terminal branching of neighboring cells during tracheal development. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.128C>G (p.A43G) alteration is located in exon 1 (coding exon 1) of the HECA gene. This alteration results from a C to G substitution at nucleotide position 128, causing the alanine (A) at amino acid position 43 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
