Genes affected
RALGAPA1 (HGNC:17770): (Ral GTPase activating protein catalytic subunit alpha 1) This gene encodes a major subunit of the RAL-GTPase activating protein. A similar protein in mouse binds E12, a transcriptional regulator of immunoglobulin genes. The mouse protein also functions in skeletal muscle by binding to the regulatory 14-3-3 proteins upon stimulation with insulin or muscle contraction. A pseudogene of this gene has been identified on chromosome 9. [provided by RefSeq, Oct 2016]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RALGAPA1. . Gene score misZ 3.5271 (greater than the threshold 3.09). Trascript score misZ 5.347 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with hypotonia, neonatal respiratory insufficiency, and thermodysregulation, complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.32506162).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.5550C>A (p.N1850K) alteration is located in exon 36 (coding exon 36) of the RALGAPA1 gene. This alteration results from a C to A substitution at nucleotide position 5550, causing the asparagine (N) at amino acid position 1850 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
