Genes affected
PLXNA1 (HGNC:9099): (plexin A1) Predicted to enable semaphorin receptor activity. Predicted to be involved in several processes, including generation of neurons; regulation of GTPase activity; and regulation of cell shape. Predicted to act upstream of or within dichotomous subdivision of terminal units involved in salivary gland branching; neuron projection morphogenesis; and regulation of smooth muscle cell migration. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PLXNA1. . Gene score misZ 3.4482 (greater than the threshold 3.09). Trascript score misZ 4.1522 (greater than threshold 3.09). GenCC has associacion of gene with Dworschak-Punetha neurodevelopmental syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.008778155).
BP6
Variant 3-126988613-G-T is Benign according to our data. Variant chr3-126988613-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 778111.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000322 (49/152366) while in subpopulation SAS AF= 0.00352 (17/4834). AF 95% confidence interval is 0.00224.
