Genes affected
LRRFIP1 (HGNC:6702): (LRR binding FLII interacting protein 1) Enables DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein homodimerization activity. Involved in negative regulation of transcription by RNA polymerase II. Located in cytosol and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 28, 2024The c.379A>G (p.I127V) alteration is located in exon 6 (coding exon 6) of the LRRFIP1 gene. This alteration results from a A to G substitution at nucleotide position 379, causing the isoleucine (I) at amino acid position 127 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
