Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.692T>C (p.I231T) alteration is located in exon 9 (coding exon 7) of the CERS4 gene. This alteration results from a T to C substitution at nucleotide position 692, causing the isoleucine (I) at amino acid position 231 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
