Genes affected

LCORL (HGNC:30776): (ligand dependent nuclear receptor corepressor like) This gene encodes a transcription factor that appears to function in spermatogenesis. Polymorphisms in this gene are associated with measures of skeletal frame size and adult height. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

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=0.18676156).

The c.1222C>T (p.P408S) alteration is located in exon 7 (coding exon 7) of the LCORL gene. This alteration results from a C to T substitution at nucleotide position 1222, causing the proline (P) at amino acid position 408 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
