Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_001256470.2(PLEKHA5):c.932A>G(p.Gln311Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000744 in 1,613,596 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).
PLEKHA5 (HGNC:30036): (pleckstrin homology domain containing A5) Predicted to enable phosphatidylinositol phosphate binding activity. Predicted to act upstream of or within reproductive system development. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
⚠️ The allele balance in gnomAD version 4 Genomes is significantly skewed from the expected value of 0.5.

⚠️ The allele balance in gnomAD version 4 Genomes is significantly skewed from the expected value of 0.5. (p-value = 0.000000), which strongly suggests a high chance of mosaicism in these individuals.
The c.914A>G (p.Q305R) alteration is located in exon 10 (coding exon 10) of the PLEKHA5 gene. This alteration results from a A to G substitution at nucleotide position 914, causing the glutamine (Q) at amino acid position 305 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
