Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.113T>C (p.L38S) alteration is located in exon 4 (coding exon 1) of the ASNSD1 gene. This alteration results from a T to C substitution at nucleotide position 113, causing the leucine (L) at amino acid position 38 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
