Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_032744.4(ADTRP):​c.505C>A​(p.Arg169Ser) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 13/23 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

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

The c.559C>A (p.R187S) alteration is located in exon 5 (coding exon 5) of the ADTRP gene. This alteration results from a C to A substitution at nucleotide position 559, causing the arginine (R) at amino acid position 187 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
