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 1 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 5.3709 (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=0.17796808).

The c.6107C>T (p.S2036F) alteration is located in exon 40 (coding exon 40) of the RALGAPA1 gene. This alteration results from a C to T substitution at nucleotide position 6107, causing the serine (S) at amino acid position 2036 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
