Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 08, 2021The c.627G>T (p.Q209H) alteration is located in exon 9 (coding exon 7) of the CERS4 gene. This alteration results from a G to T substitution at nucleotide position 627, causing the glutamine (Q) at amino acid position 209 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
