Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.109C>A (p.R37S) alteration is located in exon 1 (coding exon 1) of the UNC119B gene. This alteration results from a C to A substitution at nucleotide position 109, causing the arginine (R) at amino acid position 37 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
