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 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, LRRC4C
• BP4: Computational evidence support a benign effect (MetaRNN=0.07377106).

The c.1810C>T (p.P604S) alteration is located in exon 2 (coding exon 1) of the LRRC4C gene. This alteration results from a C to T substitution at nucleotide position 1810, causing the proline (P) at amino acid position 604 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
