Genes affected

FILIP1 (HGNC:21015): (filamin A interacting protein 1) This gene encodes a filamin A binding protein. The encoded protein promotes the degradation of filamin A and may regulate cortical neuron migration and dendritic spine morphology. Mice lacking a functional copy of this gene exhibit reduced dendritic spine length and altered excitatory signaling. [provided by RefSeq, Oct 2016]

TMEM30A-DT (HGNC:48985): (TMEM30A divergent transcript)

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.087718815).

The c.2877C>A (p.N959K) alteration is located in exon 5 (coding exon 4) of the FILIP1 gene. This alteration results from a C to A substitution at nucleotide position 2877, causing the asparagine (N) at amino acid position 959 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
