• chr1-39897649-A-C
• NM_001033081.3:c.818T>G

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_001033081.3(MYCL):​c.818T>G​(p.Val273Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V273A) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: MYCL NM_001033081.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.105

Genes affected

MYCL (HGNC:7555): (MYCL proto-oncogene, bHLH transcription factor) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within regulation of inner ear auditory receptor cell differentiation. Located in chromosome and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

MYCL-AS1 (HGNC:40386): (MYCL antisense RNA 1)

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.049982816).
