• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: -0.154

Genes affected

ADTRP (HGNC:21214): (androgen dependent TFPI regulating protein) Enables hydrolase activity. Involved in several processes, including cell migration involved in sprouting angiogenesis; negative regulation of secretion by cell; and positive regulation of macromolecule metabolic process. Located in caveola and cell surface. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.049832404).

The c.77A>G (p.Q26R) alteration is located in exon 1 (coding exon 1) of the ADTRP gene. This alteration results from a A to G substitution at nucleotide position 77, causing the glutamine (Q) at amino acid position 26 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
