Genes affected
YIPF3 (HGNC:21023): (Yip1 domain family member 3) Predicted to be involved in cell differentiation. Located in Golgi apparatus and transport vesicle. [provided by Alliance of Genome Resources, Apr 2022]
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]

The c.974T>C (p.M325T) alteration is located in exon 9 (coding exon 9) of the YIPF3 gene. This alteration results from a T to C substitution at nucleotide position 974, causing the methionine (M) at amino acid position 325 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
