Genes affected

PELO (HGNC:8829): (pelota mRNA surveillance and ribosome rescue factor) This gene encodes a protein which contains a conserved nuclear localization signal. The encoded protein may have a role in spermatogenesis, cell cycle control, and in meiotic cell division. [provided by RefSeq, Jul 2008]

ITGA1 (HGNC:6134): (integrin subunit alpha 1) This gene encodes the alpha 1 subunit of integrin receptors. This protein heterodimerizes with the beta 1 subunit to form a cell-surface receptor for collagen and laminin. The heterodimeric receptor is involved in cell-cell adhesion and may play a role in inflammation and fibrosis. The alpha 1 subunit contains an inserted (I) von Willebrand factor type I domain which is thought to be involved in collagen binding. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.99

The c.1081G>A (p.G361R) alteration is located in exon 3 (coding exon 2) of the PELO gene. This alteration results from a G to A substitution at nucleotide position 1081, causing the glycine (G) at amino acid position 361 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
