Genes affected

LRRC73 (HGNC:21375): (leucine rich repeat containing 73)

LRRC73 links:

POLR1C (HGNC:20194): (RNA polymerase I and III subunit C) The protein encoded by this gene is a subunit of both RNA polymerase I and RNA polymerase III complexes. The encoded protein is part of the Pol core element. Mutations in this gene have been associated with Treacher Collins syndrome (TCS) and hypomyelinating leukodystrophy 11. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Ambry Genetics

Aug 27, 2024

The c.70G>A (p.G24S) alteration is located in exon 1 (coding exon 1) of the LRRC73 gene. This alteration results from a G to A substitution at nucleotide position 70, causing the glycine (G) at amino acid position 24 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
