Genes affected
RNASE13 (HGNC:25285): (ribonuclease A family member 13 (inactive)) Predicted to enable nucleic acid binding activity. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]
NDRG2 (HGNC:14460): (NDRG family member 2) This gene is a member of the N-myc downregulated gene family which belongs to the alpha/beta hydrolase superfamily. The protein encoded by this gene is a cytoplasmic protein that may play a role in neurite outgrowth. This gene may be involved in glioblastoma carcinogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2017]
TPPP2 (HGNC:19293): (tubulin polymerization promoting protein family member 2) Enables tubulin binding activity. Involved in regulation of flagellated sperm motility. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2023The c.83G>A (p.G28D) alteration is located in exon 2 (coding exon 1) of the RNASE13 gene. This alteration results from a G to A substitution at nucleotide position 83, causing the glycine (G) at amino acid position 28 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
