Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 05, 2024The c.1319G>A (p.G440E) alteration is located in exon 5 (coding exon 4) of the LRRC24 gene. This alteration results from a G to A substitution at nucleotide position 1319, causing the glycine (G) at amino acid position 440 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
