Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.541C>T (p.H181Y) alteration is located in exon 4 (coding exon 4) of the UNC119B gene. This alteration results from a C to T substitution at nucleotide position 541, causing the histidine (H) at amino acid position 181 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
