not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 22, 2023The c.491C>T (p.T164I) alteration is located in exon 4 (coding exon 4) of the CCNL1 gene. This alteration results from a C to T substitution at nucleotide position 491, causing the threonine (T) at amino acid position 164 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
