Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 27, 2022The c.755T>C (p.I252T) alteration is located in exon 4 (coding exon 4) of the ACSS3 gene. This alteration results from a T to C substitution at nucleotide position 755, causing the isoleucine (I) at amino acid position 252 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
