Genes affected
ANKRD23 (HGNC:24470): (ankyrin repeat domain 23) This gene is a member of the muscle ankyrin repeat protein (MARP) family and encodes a protein with four tandem ankyrin-like repeats. The protein is localized to the nucleus, functioning as a transcriptional regulator. Expression of this protein is induced during recovery following starvation. [provided by RefSeq, Jul 2008]
ANKRD39 (HGNC:28640): (ankyrin repeat domain 39) Predicted to contribute to ubiquitin-protein transferase activity. Predicted to be involved in protein K6-linked ubiquitination. Predicted to be part of BRCA1-A complex and BRCA1-BARD1 complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2024The c.905G>A (p.R302H) alteration is located in exon 9 (coding exon 9) of the ANKRD23 gene. This alteration results from a G to A substitution at nucleotide position 905, causing the arginine (R) at amino acid position 302 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
