Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2024The c.1001C>T (p.S334L) alteration is located in exon 6 (coding exon 6) of the YTHDC1 gene. This alteration results from a C to T substitution at nucleotide position 1001, causing the serine (S) at amino acid position 334 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
