Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2021The c.104C>T (p.P35L) alteration is located in exon 2 (coding exon 2) of the IGSF6 gene. This alteration results from a C to T substitution at nucleotide position 104, causing the proline (P) at amino acid position 35 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
