Genes affected

LRRC4C (HGNC:29317): (leucine rich repeat containing 4C) NGL1 is a specific binding partner for netrin G1 (NTNG1; MIM 608818), which is a member of the netrin family of axon guidance molecules (Lin et al., 2003 [PubMed 14595443]).[supplied by OMIM, Mar 2008]

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=0.19011584).

The c.1093G>A (p.V365I) alteration is located in exon 2 (coding exon 1) of the LRRC4C gene. This alteration results from a G to A substitution at nucleotide position 1093, causing the valine (V) at amino acid position 365 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
